Im having a sharp pain in my head and blurred or spotted vision since last night. i had a concussion from an mva on 4/4/13?

Head symptoms: If your symptoms started last night but before that you were fine and recovered fully from the mva mentioned, i doubt your present condition has to do with the mva. If the headache gets worse and vision changes persist or worse or other symptoms occur, see your doc promptly. You may be having a migraine headache. Try excedrin or Ibuprofen first, cool compress, dark room and see if it works.
