Quick Answer
Yes. Autoimmune diseases can cause or contribute to peripheral neuropathy.
In autoimmune disease, the immune system—which normally protects the body from infection—mistakenly targets the body’s own tissues.
In some conditions, that immune activity can affect:
- Peripheral nerves
- The insulation surrounding nerves
- Small sensory fibers
- Blood vessels supplying nerves
- Autonomic nerves
Symptoms may include:
- Numbness
- Tingling
- Burning
- Electric or shooting pain
- Increased sensitivity
- Weakness
- Balance problems
- Changes in sweating
- Dizziness when standing
- Digestive or other autonomic symptoms
But autoimmune neuropathy is not one single disease.
The pattern of nerve involvement matters tremendously.
What Is an Autoimmune Disease?
Your immune system has an enormous job.
It identifies and attacks things that may harm you, such as certain:
- Viruses
- Bacteria
- Other infectious organisms
Normally, it distinguishes between foreign threats and your own tissues.
In autoimmune disease, that recognition system becomes disrupted and the immune system attacks parts of the body it should normally leave alone.
Depending on the disease, autoimmune activity may affect:
- Joints
- Skin
- Thyroid
- Intestines
- Blood vessels
- Muscles
- Nervous system
Sometimes peripheral nerves become involved.
How Can Autoimmune Disease Damage Nerves?
There isn’t one single mechanism.
Depending on the autoimmune disorder, the immune system may attack:
- Components of peripheral nerves
- Myelin, the insulating covering around certain nerve fibers
- Structures associated with nerve function
- Small sensory or autonomic nerve fibers
- Blood vessels supplying peripheral nerves
When blood vessels supplying nerves become inflamed—a condition called vasculitis—the nerves may not receive adequate blood flow and can become injured.
Different mechanisms create different neuropathy patterns.
Which Autoimmune Diseases Can Be Associated With Neuropathy?
Peripheral neuropathy can occur with a variety of autoimmune or inflammatory conditions.
Examples include:
- Sjögren’s disease
- Systemic lupus erythematosus
- Rheumatoid arthritis
- Certain forms of vasculitis
- Sarcoidosis
- Celiac disease
- Other systemic autoimmune disorders
There are also immune-mediated disorders in which peripheral nerves themselves are major targets.
Examples include:
- Guillain-Barré syndrome
- Chronic inflammatory demyelinating polyneuropathy, or CIDP
This does not mean everyone with one of these diagnoses will develop neuropathy.
Most will not develop every possible neurological complication.
What Does Autoimmune Neuropathy Feel Like?
There is no single symptom pattern.
Depending on which nerves are affected, a patient may experience:
- Burning feet
- Numb toes
- Tingling
- Stabbing pain
- Electric sensations
- Sensitivity to light touch
- Reduced temperature sensation
- Weakness
- Foot drop
- Difficulty walking
- Balance problems
Some autoimmune neuropathies affect both sides relatively symmetrically.
Others can be surprisingly patchy or asymmetrical.
That difference can be diagnostically important.
Why Is Asymmetry Important?
Many common metabolic neuropathies—such as typical diabetic polyneuropathy—often develop relatively symmetrically.
Both feet may gradually become numb.
But certain inflammatory or vasculitic neuropathies may affect individual nerves in a more scattered pattern.
A patient might develop:
- Foot drop on one side
- Then weakness somewhere else
- Then numbness or pain in another nerve distribution
This pattern deserves careful evaluation.
What Is Mononeuritis Multiplex?
One pattern associated with certain inflammatory or vasculitic conditions is called:
Mononeuritis multiplex
Rather than affecting all peripheral nerves evenly, separate individual nerves become injured in different locations.
Symptoms may be:
- Painful
- Asymmetrical
- Patchy
- Associated with weakness
For example, one nerve in one leg may become affected, followed later by a different nerve elsewhere.
This is quite different from the slowly progressive symmetrical numbness many people associate with typical peripheral neuropathy.
What Does Vasculitis Have to Do With Nerves?
Vasculitis means inflammation of blood vessels.
Peripheral nerves depend on small blood vessels for oxygen and nutrients.
If those blood vessels become inflamed and blood flow is disrupted, the nerve can become injured.
Vasculitic neuropathy may sometimes produce:
- Significant pain
- Weakness
- Asymmetrical nerve deficits
- Relatively rapid changes
Because certain forms can cause substantial nerve damage, timely evaluation matters.
What About Small Fiber Neuropathy?
Autoimmune disease can sometimes be associated with:
Small fiber neuropathy
Small nerve fibers help carry:
- Pain
- Temperature
- Certain autonomic signals
Small fiber neuropathy may cause:
- Burning
- Stinging
- Pins and needles
- Pain from light touch
- Temperature abnormalities
Some patients also develop autonomic symptoms.
Importantly, routine nerve-conduction studies and EMG may be normal in small fiber neuropathy because those tests primarily assess larger nerve fibers.
A Normal EMG Does Not Rule Out Every Neuropathy
This is an important lesson.
A patient may say:
“My EMG was normal, so they told me my nerves are fine.”
Not necessarily.
A normal EMG and nerve-conduction study can be reassuring in certain ways.
But those tests do not evaluate every type of nerve fiber equally.
If the clinical pattern suggests small fiber neuropathy, additional evaluation may sometimes be appropriate.
What Is Sjögren’s Disease?
Sjögren’s is an autoimmune disease commonly associated with symptoms such as:
- Dry eyes
- Dry mouth
But it can affect other organs and systems as well.
Neurological complications may include different forms of peripheral neuropathy, including sensory and small-fiber patterns in some patients.
This is another reminder that an autoimmune disease affecting one obvious part of the body may also have effects elsewhere.
Can Lupus Cause Neuropathy?
Systemic lupus erythematosus—commonly called lupus—can affect many organ systems.
Peripheral nerve involvement can occur in some patients.
But if a person with lupus develops numb feet, it should not automatically be assumed that lupus is responsible.
Other causes still matter:
- Diabetes
- B12 deficiency
- Medications
- Kidney disease
- Nerve compression
- Other neurological conditions
An autoimmune diagnosis does not eliminate ordinary causes of neuropathy.
Can Rheumatoid Arthritis Cause Neuropathy?
Neuropathy can occur in people with rheumatoid arthritis for several reasons.
Possible contributors may include:
- Nerve compression from joint or tissue changes
- Vasculitic complications in selected cases
- Other medical conditions
- Medication-related factors
For example, hand numbness in someone with rheumatoid arthritis might result from carpal tunnel syndrome rather than generalized autoimmune neuropathy.
Again:
Where the symptoms occur matters.
What Is Guillain-Barré Syndrome?
Guillain-Barré syndrome, often abbreviated GBS, is an acute immune-mediated disorder affecting peripheral nerves.
It may occur after an infection or other immune trigger.
Symptoms can include:
- Tingling
- Weakness
- Difficulty walking
- Reduced reflexes
- Rapidly progressive weakness
Weakness may progress over hours to days and can involve the legs, arms, facial muscles, swallowing muscles, and muscles involved in breathing.
Guillain-Barré syndrome can be a medical emergency.
Rapidly progressing weakness requires urgent evaluation.
When Weakness Is an Emergency
Seek emergency medical care for symptoms such as:
- Rapidly worsening weakness
- Weakness moving upward from the legs
- New inability to walk
- Difficulty breathing
- Difficulty swallowing
- New facial weakness
- Severe new autonomic symptoms
- Rapid neurological deterioration
Do not wait for a routine neuropathy appointment.
Some neurological conditions require immediate hospital evaluation.
What Is CIDP?
CIDP stands for:
Chronic Inflammatory Demyelinating Polyneuropathy
CIDP is an immune-mediated peripheral neuropathy in which the immune system damages myelin surrounding peripheral nerves.
Unlike the more rapid course typical of Guillain-Barré syndrome, CIDP generally develops or progresses over a longer period.
Symptoms may include:
- Weakness
- Numbness
- Tingling
- Reduced reflexes
- Difficulty walking
- Balance problems
CIDP is important to recognize because specific immune treatments may help appropriately diagnosed patients.
Why CIDP Shouldn’t Be Self-Diagnosed
A patient may read:
“CIDP causes weakness and numbness.”
Then think:
“That’s exactly what I have.”
But weakness and numbness occur in many disorders.
Diagnosing CIDP may involve:
- Neurological examination
- Nerve-conduction studies
- EMG
- Laboratory testing
- Sometimes spinal-fluid analysis
- Additional testing depending on the case
This diagnosis belongs in the hands of clinicians experienced in neuromuscular disease.
Can Autoimmune Neuropathy Affect the Autonomic Nerves?
Yes.
Some autoimmune neuropathies can involve autonomic nerve fibers.
The autonomic nervous system helps regulate functions you don’t consciously control, including:
- Blood pressure
- Heart rate
- Sweating
- Digestion
- Bladder function
- Sexual function
Possible symptoms may include:
- Dizziness when standing
- Abnormal sweating
- Digestive changes
- Changes in bladder function
- Other autonomic problems
These symptoms deserve appropriate evaluation.
Could an Autoimmune Neuropathy Be Painful?
Yes.
Some inflammatory and small-fiber neuropathies can be quite painful.
Patients may describe:
- Burning
- Stabbing
- Electrical pain
- Deep aching
- Severe sensitivity
Pain intensity alone does not tell us the cause.
But a new, painful, rapidly evolving, or asymmetrical neuropathy may deserve particularly careful investigation.
How Is Autoimmune Neuropathy Diagnosed?
There is no single test called:
“The Autoimmune Neuropathy Test.”
Evaluation may involve:
- Detailed medical history
- Neurological examination
- Reflex testing
- Strength testing
- Sensory testing
- Nerve-conduction studies
- EMG
- Blood tests
- Evaluation for autoimmune markers
- Testing for nutritional and metabolic causes
- Skin biopsy for selected small-fiber cases
- Autonomic testing in selected patients
- Imaging when appropriate
- Spinal-fluid testing in selected disorders
- Occasionally nerve or other tissue biopsy in specialized situations
The testing should be guided by the patient’s pattern rather than ordering every possible autoimmune laboratory test indiscriminately.
Why Not Just Order Every Autoimmune Test?
Because more testing isn’t always better testing.
Autoimmune blood tests can sometimes be:
- Nonspecific
- Weakly positive in people without the disease
- Difficult to interpret without the right clinical context
A positive antibody does not automatically prove that an autoimmune disease caused the neuropathy.
The better approach is:
Start with the clinical pattern, then choose tests that answer specific questions.
Can Autoimmune Neuropathy Be Treated?
Some autoimmune neuropathies can respond to treatment directed at the immune process.
Depending on the specific diagnosis, specialists may use therapies such as:
- Corticosteroids
- Intravenous immune globulin, or IVIG
- Plasma exchange
- Other immunomodulating or immunosuppressive treatments
But these treatments are not general treatments for ordinary peripheral neuropathy.
They have significant potential risks and should be used only when medically appropriate.
Why the Exact Diagnosis Matters
Imagine treating diabetic neuropathy with aggressive immune-suppressing medication.
That would make little sense.
Now imagine missing a treatable inflammatory neuropathy because everyone assumed:
“It’s just diabetes.”
That could also be harmful.
This is why the goal isn’t merely to identify neuropathy.
It is to identify the type and cause whenever possible.
Don’t Assume Every Symptom Comes From Your Autoimmune Disease
Patients with established autoimmune disease sometimes fall into the same trap we discussed with thyroid disease.
“I have lupus, so this must be lupus.”
“I have rheumatoid arthritis, so this must be rheumatoid arthritis.”
Maybe.
But perhaps the numbness is from:
- Diabetes
- B12 deficiency
- Carpal tunnel syndrome
- Lumbar nerve compression
- Kidney disease
- Medication effects
Existing diagnoses provide clues.
They don’t eliminate other possibilities.
Could Medications for Autoimmune Disease Affect the Nerves?
Potentially, depending on the medication.
Some treatments used for autoimmune disease can have neurological side effects or other effects that need monitoring.
On the other hand, appropriate treatment of an autoimmune disorder may protect nerves when the immune disease itself is causing nerve injury.
This creates an important balance.
Never stop immune-modifying medication because you suspect a side effect without discussing it with the prescribing specialist.
How We Evaluate Possible Autoimmune Neuropathy at Advanced Integrated Medical
When a patient’s symptoms suggest something beyond typical metabolic neuropathy, I want to know:
- Is there a known autoimmune disease?
- Did symptoms begin suddenly or gradually?
- Are they symmetrical?
- Is one side much worse?
- Is there significant pain?
- Is weakness developing?
- Are reflexes changing?
- Is there foot drop?
- Are the hands involved?
- Are autonomic symptoms present?
- Has an EMG or nerve-conduction study been performed?
- Could this be small fiber neuropathy?
- Are diabetes, B12 deficiency, thyroid disease, kidney disease, medications, or other causes present?
When the pattern raises concern for an inflammatory or immune-mediated neuropathy, appropriate neurological or rheumatological referral may be necessary.
Recognizing when to refer is part of good patient care.
Treatment Depends on the Cause
Autoimmune neuropathy is not one condition, so there is no one treatment.
Depending on the diagnosis, care may involve:
- Treating the underlying autoimmune disorder
- Neurology evaluation
- Rheumatology evaluation
- Immunotherapy when medically indicated
- Treatment of neuropathic pain
- Physical therapy
- Strength rehabilitation
- Balance training
- Fall prevention
- Foot protection
- Management of other contributing neuropathy causes
The treatment should match the disease.
About Dr. Dee
Dr. D. Scott (“Dee”) Stevens has spent nearly four decades helping patients with peripheral neuropathy, chronic pain, musculoskeletal disorders, sports injuries, and regenerative medicine.
Throughout his career, he has cared for patients from all walks of life—including professional, collegiate, and Olympic athletes, professional football players, Major League Baseball players, professional boxers, and MMA fighters.
One lesson I’ve learned is that not every neuropathy belongs in the same treatment box.
A patient with slowly progressive diabetic sensory neuropathy is very different from a patient developing rapidly progressive weakness from an inflammatory neurological disorder.
Both involve nerves.
But they may require completely different care.
Dr. Dee’s Clinical Pearl
When evaluating neuropathy, I pay particular attention when the story includes:
Rapid progression
Significant weakness
Marked asymmetry
Foot drop
Loss of reflexes
Autonomic changes
Those findings don’t automatically prove autoimmune neuropathy.
But they may tell us:
“This patient needs a different level or direction of evaluation.”
Knowing when something doesn’t fit the ordinary pattern is just as important as recognizing what does.
Dr. Dee’s Office Conversation
Patient: “Doctor, I have an autoimmune disease. Is that why my feet burn?”
Dr. Dee: “It could be related, but I wouldn’t assume that yet.”
Patient: “Why not?”
Dr. Dee: “Because autoimmune disease can affect nerves in several different ways, but burning feet can also come from diabetes, B12 deficiency, small fiber neuropathy, medications, and other causes.”
Patient: “So what do we do?”
Dr. Dee: “We look at the pattern first. Then we decide which questions need answering.”
Facing One of the Biggest Fears
“If My Immune System Is Attacking My Nerves, Am I Going to Keep Getting Worse?”
Not necessarily.
The outcome depends heavily on the specific diagnosis.
Some immune-mediated neuropathies may respond to treatment.
Others may stabilize.
Recovery may be partial or substantial depending on the condition and degree of nerve damage.
But this is exactly why identifying unusual patterns early matters.
Don’t assume:
“Autoimmune means unstoppable.”
And don’t assume:
“Neuropathy means nothing can be done.”
Get the correct diagnosis first.
Patient Success Principle #26
Pay Attention When the Pattern Changes
If your neuropathy has been stable for years and suddenly something changes, don’t automatically assume:
“My neuropathy is just getting worse.”
Pay attention to:
- New weakness
- New foot drop
- Rapid progression
- Symptoms appearing in unusual places
- One side becoming much worse
- New balance problems
- New autonomic symptoms
A changing pattern deserves a fresh look.
Your previous diagnosis may still be correct.
But the new symptom may be telling us something new.
Ask Dr. Dee
“Doctor, should everyone with unexplained neuropathy be tested for autoimmune disease?”
Not necessarily.
Testing should be guided by:
- Symptoms
- Neurological pattern
- Medical history
- Examination findings
- Other possible causes
Ordering every autoimmune test on every neuropathy patient may produce confusing results without providing useful answers.
Good testing begins with a good question.
Lesson I’ve Learned in Nearly 40 Years
Know When the Pattern Doesn’t Fit
Medicine becomes much easier when every patient looks exactly like the textbook.
Patients rarely cooperate with that idea.
Over nearly four decades, I’ve learned to pay attention when something doesn’t fit.
A neuropathy that is:
Too fast.
Too weak.
Too asymmetrical.
Too painful.
Too unusual.
may be telling us to widen the investigation.
You don’t need to know the answer immediately.
But you do need to recognize when the ordinary answer isn’t enough.
The Hope Principle
The word autoimmune can frighten people.
It can sound as though the body has turned against itself and nothing can be done.
But autoimmune medicine has changed tremendously.
Many immune-mediated disorders can be evaluated, monitored, and treated.
That doesn’t mean every autoimmune neuropathy can be completely reversed.
It means the diagnosis matters.
The sooner we understand what kind of neurological problem we’re dealing with, the better positioned the healthcare team is to make appropriate decisions.
Hope sometimes begins by recognizing that this isn’t “just neuropathy”—and finding the right person to evaluate why.
“I believe the best healthcare decisions are made when patients understand their condition. My job isn’t simply to treat symptoms—it’s to help you understand why they’re happening and what your options are.”
— Dr. D. Scott (“Dee”) Stevens
Frequently Asked Questions
Can autoimmune disease cause peripheral neuropathy?
Yes. Several autoimmune and inflammatory diseases can affect peripheral nerves.
Which autoimmune diseases are associated with neuropathy?
Examples include Sjögren’s disease, lupus, rheumatoid arthritis, vasculitis, sarcoidosis, celiac disease, and certain immune-mediated neurological disorders.
Can autoimmune disease cause small fiber neuropathy?
Yes. Some autoimmune disorders are associated with small fiber neuropathy.
Can autoimmune neuropathy cause foot drop?
Certain inflammatory, vasculitic, or motor neuropathies can produce focal weakness including foot drop. New foot drop deserves prompt evaluation.
What is Guillain-Barré syndrome?
GBS is an acute immune-mediated peripheral nerve disorder that can cause rapidly progressive weakness. Severe cases may affect breathing or swallowing and require urgent hospital care.

If you have an autoimmune disease and develop numbness, burning, tingling, or weakness, don’t automatically assume:
“It’s my autoimmune disease.”
But don’t automatically dismiss the connection either.
Instead, ask:
What is the pattern?
How quickly is it changing?
Is weakness present?
Is it symmetrical?
Could small fiber neuropathy be involved?
Could another cause explain it?
Do I need additional neurological evaluation?
At Advanced Integrated Medical, we believe understanding the pattern helps determine the next step.
Because sometimes neuropathy is slowly progressive and familiar.
Sometimes it is caused by something unexpected.
And sometimes the most important thing we can recognize is:
“This doesn’t look like ordinary neuropathy—and we need to find out why.”
