I have a pulsating or pressure pounding in my head. It has no pain or sound. It disrupts my hearing as it goes on & off. Some of the triggers seam to be talking on the phone, laughing hard, a room full of a lot of noise, alcohol, or maybe just nothing. Some times it last for hours and other times it will last for minutes. It has been going on for years, around thirty . It seemed to start when I came to Florida to live. No Dr. will pay any attention to me even though it has been a real heart ship for me.
