I know I have asked about feet before, but for those of you that have had problems with you feet. Did going on a biologic help? I never had a problem with my feet until I went on a biologic. It was just in my left foot now, its in my right. I am almost positive that this is a sideeffect of the med for me. I have developed carpal tunnel and terrible tennis elbow, as well as tinnitus. I am wondering should I try I diff. biologic. I was hoping over time it would go away, the severity does seem to come and go. I can sure tell the diff. it I dont get a good nights sleep. I have always been and very anal, type A, control freak. this is driving me crazy, and I feel helpless. The doctors dont seem to know squat either. when I came back to see my Rheumy after the first round of enbrel, I could tell by looking in her eyes, she had know idea what was going on. She expected me to come back and be fixed.
