I was going to post an encouragement to exercise: even with both knees replaced, a hip replacement, an ankle fusion, and just turning 60 I've managed to ride my bicycle 10 or more miles a day each day this summer and I feel better than I've felt for a long time. I'm on Methotrexate, Tramadol, and Naproxen. Even though I can't walk far, on a bicycle I do very well.
Until last night. Haven't had a bad flare for a little while and my back flared last night. Oh well, it's happened before and I'll survive, though my cursing and moaning is hard on my wife.
Back to the exercise stuff: find something you can do and do it every day! (unless you are flaring badly) I think you'll feel the difference!
