meniere's disease
"I have been dealing with symptoms of Meniere's Disease for 30 years and until three years ago no Dr. could properly diagnose the issue. 
When I was 5 years old I suffered a concussion, when I was 13 years old I suffered another concussion from a 90 mph fastball to the head.  Shortly after the incident at 13 years old I started having intermittent & recurring symptoms of vertigo & hearing loss in my left ear (same side as both injuries).  My parents thought I was a typical stubborn teen until they took me to have my hearing tested and found I had 30db of hearing loss. Two years ago I started experiencing unexplained falls and roaring in my ear.  The Dr found 60 Db & said it is Meniere's. The Dr prescribed low dose Valium. It changed my life!"
