Today in Phy. Ed class I got hit with a fully filled volleyball right on my thumb at the part where it connects to the rest of my hand. It hurt really bad when it happened and still hurts now, 6 hours later. I didn't do anything about it, just went on with the rest of the school day. Ever since it happened it has some swelling and a small part is bruised toward the outer part of the bottom of my thumb. Also towards the bottom of my palm one of the veins/arteries is darker then the rest. Do I have to go to the doctor? I really don't do well in hospitals, I just can't take it. Nothing like this has ever happened to the hand that has my hurt thumb.
