I am 61 year old female. for the last 3 weeks my hands have been aching and are slightly swollen. I am also getting cramps in my feet. I find it diificult to type this and playing the piano hurts. 5 years ago a dr. had me taking enbrel shots in my stomach for RA. I did it for 6 months and symptoms cleared up. My tests never said I had RA, but he said I probably did. Could that be true? or is it something else. Help!
