I have had joint pain in a few joints in my hands for the last couple of years, mainly in the lower thumb joints. I am a 36 year old female. I have never had the stiffness, fevers, fatigue, weakness and swelling associated with RA. I do have a swollen joint in my wrist right now but I think I may have injured it. I'm not overweight. For the last three months I've also been having pain in the first knuckle of my right index finger.
What else could it be besides RA? Can someone my age develop osteoarthritis?
