I rode a dirt bike for a cumulative 16 hrs over the weekend and my left hand, mainly my thumb, is wrecked and I can't make it move or do things like make sandwiches or fold laundry! It's not painful, which wouldn't bother me anyway 'cause pain don't hurt, but I need a working opposable thumb!!! This was my first time riding in like forever and I am wondering, will my thumb ever work again? Is this normal/typical?
