<t>My daughter did the same thing. She actually bit her entire index fingernail off and kept biting over and over after that!<br/> <br/> I took her to the neurologist and I never got a straight answer to why this was happening. (I've since changed Drs.) I believe she was getting a tingling sensation...

They do the same to my daughter their too. Does you see Dr. Adelson? Our next trip won't be until the end of Sept. I've got her in PT/OT every week trying to avoid the surgery... Her range of motion hasn't increased much though. We still have alot of time to work on it though.
