[|Human|] My son who is 44 years old has recently been diagnosed with RA.  He has been to a dermatologist also for a hive-like rash all over his body along with "knots" on his legs, thighs, and back of his head.  This doctor did a culture and was determined that is not an allergic reaction, but a part of the RA he has been diagnosed with.  I am concerned about the knots and rash.  It is currently under control with steroids.  What else could this be and is this serious?
[|AI|]  Hello, Thanks for the query. These knot like lesions are rheumatoid nodules. The lesions keep coming and going. In fact These are characteristic feature of RA. You don't need to worry much. These are not dangerous. Treatment is symptomatic. Dose of steroids is increased or decreased according to severity of disease. Please meet a dermatologist for exact diagnosis. Let me know if you have any other doubt. You can ask a direct question to me on this forum, following the below link.https://urldefense.com/v3/__http://www.ChatDoctor .com/doctors/ Chat Doctor.
