FMS and lupus are both hard to diagnose, and because their primary symptoms can be very similar, people with FMS are sometimes misdiagnosed as having lupus, and vice versa.
A sizable number of people have both conditions, which complicates diagnosis and treatment. Therefore, it’s important for those with FMS to be familiar with the symptoms of lupus.
Lupus, also known as systemic lupus erythematosus (SLE), is an autoimmune disease. That means your immune system malfunctions and attacks your healthy tissues as if they were a dangerous virus or bacteria. Lupus can take different forms and can attack any part of your body. Its most common targets are the skin, joints, heart, lungs, blood, brain and kidneys. We have several treatment options for lupus, but there’s no cure.
Most people with lupus can manage their symptoms to some degree and don’t face life-threatening complications. Those with certain complications, particularly kidney involvement, have a lower survival rate.
Treatment generally involves suppressing the immune system, which slows down the attack on whatever parts of your body are involved.
However, it also increases the risk of serious infection.
Lupus causes inflammation, pain, and tissue damage. Its course is unpredictable, and symptoms can come and go in a series of flares and remissions.
While lupus and FMS share some features, FMS is not known to be an autoimmune disease, and it doesn’t cause tissue damage.
Some cases of FMS may involve inflammation, but the research on that is still in the early stages.
Fibromyalgia and Lupus Risks
People with FMS don’t appear to be at a higher risk of developing lupus, but people with lupus do have an elevated risk of developing FMS. So far, we don’t know why. It’s possible that the pain of lupus leads to central sensitization, which is a key feature of FMS. Until researchers pin down the causes of these conditions, we likely won’t understand their relationship to each other.

Like FMS, lupus is hard to diagnose. No one test can pinpoint it, and because symptoms can vary widely from one patient to another, it’s hard for a doctor to recognize.
Before diagnosing lupus, your doctor will likely give you a physical exam, look at your flare patterns, run tests to rule out diseases with similar symptoms and do what’s called an “antinuclear antibody” (ANA) blood test.
An ANA checks for auto-antibodies, which are part of the autoimmune response. If your ANA test is positive or shows certain patterns, your provider may order additional auto-antibody tests:
- Anti-Smith (anti-Sm)
If those tests are positive, it usually results in a diagnosis of lupus.
If you’ve been diagnosed with FMS but haven’t had an ANA, you may want to ask your doctor to run the test to rule out lupus or other autoimmune disorders.
Symptoms of FMS & Lupus
Lupus and FMS have several features and associations in common, including:
- Muscle and joint pain
- Memory problems
- Flares and remissions
Lupus, however, comes with inflammation in the joints, while inflamed joints aren’t.
Other features of lupus that aren’t part of FMS include:
- Butterfly-shaped rash on the cheeks and bridge of the nose
- Skin lesions that appear or get worse with sun exposure
Both conditions are associated with many other symptoms as well.

Lupus isn’t a one-treatment-fits-all condition. The most common drugs for treating lupus include:
- Non-steroidal anti-inflammatories (NSAIDs)
Lifestyle changes that can help alleviate lupus symptoms include:
- Stress reduction
- Healthy diet
- Moderate exercise
- Not smoking
- Reduced sunlight exposure
It takes some experimentation to find the combination of medications and lifestyle changes that work best for you.

Lupus vs. Fibromyalgia Treatments
While it’s certainly more difficult to treat two conditions, lupus treatments don’t generally have a negative impact on FMS, with the possible exception of steroids. Some FMS experts believe that steroids can exacerbate FMS symptoms. Be sure to check with your doctor and pharmacist about possible drug interactions, as well.
The lifestyle changes recommended for the two conditions are very similar, so you could get a double benefit from making those changes.
