My Husband Was Hit With A Line Drive While He

My husband was hit with a line drive while he was pitching at softball slightly below the knee, He is having throbbing, pain while applying pressure and his entire leg from knee down is twice the size of his other leg. He had reconsructive vein repair after being a victim of a robbery and being shot behind his knee on this leg. He had vein graphs they used veins from the other leg thigh area. To release the swelling the cut both sides of his calf and was on a wound vac until he healed. Should he go to the doctor for an xray
