Hi. I had one of my hands seize up. I couldn't move my fingers. I took naproxen for a couple of days and eventually the stiffness and pain subsided. I also have feelings that my legs are a bit jelly like along with my arms and fingers which I wonder if this maybe why I am so clumsy, knocking things over, tripping up etc. I suppose the other way to explain it would be to say a slight tremoring. has anyone experienced anything like this?
