Anyone alse on here get cluster headaches? Not Migraines..

I get silent migraine's I start seeing half of everything then it turns into a flashing light and I can't see anything until it clears up. It usually last 30 minutes or so but has lasted over an hour. The headache comes afterwards and I hate them, I had the first one when I was 16, and have had them about once or twice a year since.
Well that sounds just lovely, losing your eyesight followed by a pile of pain. Welcome to the 'my own head hates me' club. I know it's a dumb question that people always ask.. but you have seen a Dr. or 10 about it, right?
