4 Diseases that mimic Rheumatoid Arthritis

Rheumatoid arthritis (RA) can be a diagnostic challenge. There is no definitive test to prove RA. In addition, there are other conditions that present with the same symptoms.

If your doctor suspects that you have rheumatoid arthritis, they must have to first rule out other diseases that mimic it. Here are some diseases that mimic RA.

  • Post-Viral Arthritis – Viral infections can cause a temporary condition – polyarthritis. The condition looks like rheumatoid arthritis. Parvovirus B19, hepatitis, and HIV can cause this condition.


  • Seronegative Spondyloarthritis – This is a group of rheumatic conditions that lead to inflammation in the spine. One example is Psoriatic arthritis. If it presents without a rash, it can be hard to differentiate it from RA. Ankylosing spondylitis and IBS can also mimic RA.


  • Lupus – Lupus is an autoimmune disease that affects the joints. It can cause deformities that look like the joint damage in RA. The distinguishing factor is that with lupus, the deformity comes from the tendons and ligaments rather than the joints, which is the case in RA.


  • Scleroderma – This condition presents as joint pain, skin tightening, heartburn, and Raynaud’s disease. Scleroderma can be ruled out with blood tests and serologic studies.

If you or a loved one is experiencing any of the above symptoms, don’t ignore them. Seek treatment from a pain specialist immediately. A pain specialist is trained and experienced in diagnosing and treating all kinds of pain disorders.
