Im a 32yr old white male. Very active and fit. I take no medications and am in overall great health. About a week ago I got a sensation in my left upper but that felt like someone stabbed me with a needle . Lasted about 15 sec and went away. It has happened randomly now for the last week. Very isolated and intense pain. No more than. About 15 sec. No other pain what so ever. Happens when standing sitting driving laying down. Can’t ” make” it happen. Sciatica?
