Hi Everyone, I'm new here, and hoping that someone might be able to help. About 3 weeks ago i started having really bad wrist pain under my thumb joint, and despite splinting, non-usage, icing, heating, ibuprofen, and doing nothing, I still feel a sharp pain when I move my wrist, say, to turn a doorknob counterclockwise, or open a jar. I've been told I may be suffering from de Quervain's syndrome. Any suggestions or experience to share??? Help!
