I'm 17 years old, for the past few weeks I've been getting a really annoying pain in my head, everyday, from when i wake up to when i go to sleep, it feels like my brain is swelling and pushing against my skull, it hurts to touch and loud noises hurt my ears, the light doesn't affect me so i ruled out migraines, i'm quite concerned as i haven't whacked my head for months and months, so yes i'm concerned.
