Back in 2006 I suffered from a contusion, it knocked me out and left me very light headed. I went to get an MRI and doctor said everything was okay. I suffered from bad balance for weeks (vertigo?) it took months to fully recover. After that every once in a while I feel vertigo and dizzy spells. However, for the past month or so Ive had Vertigo and I feel it everytime I tilt my head to the left side or lay on that side while in bed. Is this still symptoms from the Contusion? will it ever go away?
