Sounds like mirgraines, I'd see a doctor. When I get them (I'm 14), the only that really helps is to lay down in a dark quite room. Tylenol doesn't do ANYTHING for mine. What I usually take is Excedrine Migraine Relief but I don't know if you can, do to your hbp. I know there are a TON of perscription meds to help with headaches. I'm sure there's one that a doc can give you. So I'd see a doctor. Headaches are no fun. It's hard to concentrate, much less function right if you have one.
