I have a severe headache in the lower right hemisphere of my head and it's been lasting for around six hours so far. It's more of a pain like something is pushing against it or there's a stabbing pressure in that area. I don't have any other symptoms except when I cough it's hurts more and I'm a little bit dazed and uncomfortable.
When I lie down, the pain goes away but once i get up the pain comes back really badly.
could this be a blood clot?
Sounds like a migraine. Stay down, drink water, keep taking advil or aspirin or tylenol, whichever you prefer. If tomorrow it's the same, I'd see a doctor.
