I was in a A A 8-2-2016 and suffered a bad neck whiplash? and then I fell out of my s.u.v. 10-3-2016 and broke my humerous, left arm, but I had this enormous bump on the back of my head the size of a goose egg., the hospital ignored this, I have horrible dizzy spells, my head feels like i am swimming and when I get up I almost lose my balance, and am very careful with this NEW thing.,Do I have vestibular?
