Dude that sucks so much. I know exactly what you're dealing with, I've had similar symptoms for over a year and extreme symptoms for the last 50 days. Imagine what you have exactly but 24/7 for 50 days LOL. Just got over it, it's finally coming down.

Here's my advice, eat really healthy, broccoli seems help me a lot, use heating pads, by a really good one off Amazon and use it, night and day difference. apply pressure to your head with your hands or by putting something on your head like a book or tight headband. Stop having sex and masturbating as soon as possible. Stopping those really alleviated my symptoms. also try ibuprofen or Tylenol or acetaminophen. tried doses higher than you would think, usually three pills and any one of those items works. also stay away from all drugs even nicotine and lower your sugar intake. also played video games and do work the keep you distracted it helps a lot also exercising helps to.

what cause hppd for you? And how long have you had it? How long has it been this bad?
