Hello. Two weeks ago I was on a bus. To stand up, I yanked myself up by one arm in one fasts motion and hit my head on the ceiling of the bus. I did not feel well immediately, but my pupils were not abnormal. I believe I may have had a concussion because I have numerous before and I was dizzy, nauseated, and out of it for several days. My main complaint was that my head was full of pressure. It has been two weeks and my head is so full of pressure that it hurts to lie down to go to sleep at night. I have constant headaches and migraines and my head is very tender to the tpuch. I also can t focus on anything or perform daily tasks. What do you think is going on with my brain?
