Sure, they don't know for sure that it's all family related. There are even theories out there that it can be caused by a virus. Then there's always lymes disease as well.
I would certainly go to the doctor to be checked out if you're experiencing all these symptoms! Do your joints swell as well? (They don't have to swell to be arthritis. Mine have swollen, but don't usually.)
No they don't usually, went to the doctors and being tested for everything. Thanks for your response. The doctors gave me pain meds for now.
RA runs in my family, but I know many, many patients who have no family history.
