Does anyone know what would cause me to suddenly start having pain in my hand when lifting? I'm getting pain in my palm thumb (ie - inside of the lower thumb/palm) when I grab the freeweights, perticularily dumbells. Am I having this pain because my hands are weak? If so, odd because I'm right handed and don't perticularily thing they would be with all my trials riding. Or, is it possible I tore something in my hand?....or something else?
