I get vertigo because of certain pitches and certain volumes. I also have had "unexplained" headaches for over a decade. I say unexplained because I have had multiple CT scans that showed no nervous system inflammations or tumors. After my daughter was born and subsequently diagnosed with Asperger Syndrome, pieces starting falling in order and I got an answer about my headaches and dizziness.

Aspergers Syndrome and other neuro-atypical syndromes can cause vestibular system problems, as well as a serious sensitivity to light and sound. Light and sound easily set off vertigo and splitting headaches in me.

Read up on Aspergers Syndrome and see if it fits you because it is a possible source of your problem. It will be immediately apparent if you're an Aspie or not once you read about it.
