hi, i hit my head on a metal bar 2 days ago. it wasnt intentionally, but i had fell to the floor and was pickedup to be put on the bed. and when i was dropped on the bed i yanked my head on a metal bar. ever since then i have had constant blurry vision, major headaches, but the headaches arent like how they usually are they feel like i cant really describe it, my eyes are sensitive to the light, and sometimes when i close them it feels like im shaking tremendouslly fast. i just turned 16 last week, and im scared. please help?
