I had a cortisone in each shoulder on 2/6/13, upon leaving the office I began shaking and got weak, I sat in the hospital lobby and wasnt getting better but didnt seem to be getting worse, I live really close to the hospital so I just wanted to go home, so I did. I slept for a few hours, I had quit shaking after I slept but the weakness was still there throughout my whole body. Now its 2/11/13 and Im still weak mostly in my thighs and its worse after exertion. I ve had cortisone shots before (not 2 at the same time) with no problems. Didnt go to ER because, well what would they do? Any ideas?
