Hello, I fell in the shower & have a big bump and bruise on the lower back side of my head close to my neck. It only hurts if I touch it & I have no other symptom associated with TBI. My neck was not showing any signs of bruising until three days after the fall. Does that mean that the bruise is draining down my neck? How concerned should I be?
