I have episodes of extreme vertigo which may last 5 to 10 minutes and longer, sometime followed by a bad headache that begins above my left temple and may go down the left side of my head to the base of my neck. I have been hit in the same are above my left temple several times through the years (cattle kicks while branding, fights, and once when I fell and hit concrete after vetigo attack. What could be wrong with me? My GP tells me that it is an inner ear infection. Severe attacks (lasting on and off several days, or more) have happened 3 times.
