My mother had a history of rheumatoid arthritis for over 20 years. Just yesterday I observed a slight pain and swelling in my knees. Could this be a sign of rheumatoid arthritis? How would it be diagnosed?
Yes, it could.
RA usually starts in the small hand joints, but can start looking like a shoulder bursitis or knee swelling. Many people have minor mechanical knee disorders that need little care. Taking fluid from your knee by a rheumatologist may be very helpful.
