At first I thought it was because it was cold but then it continued after my hands were warmed up. Its only in my right hand though. I have trouble gripping things and am having to force my hand to move. It seems to freeze up. I've been sick lately but I don't know if that has anything to do with this. I'm also only 17 years-old. Please help me figure out what's going on. Its very uncomfortable and is preventing me from doing some things.
