Just had a weird dizziness spell - while eating lunch. Came in 3 waves - small, bigger, biggest. Also felt very warm, sweaty. tightness in scalp. I am male, 64. taking terazosin for prostate. 5 10 , 203 lbs. Blood pressure 131/70 ( just did that last week). No history of problems (heart, cholesterol, blood pressure). About a year ago a hammer fell (about 4 feet) on my head.
