Hit my head again - didnt think much of it because compared to previous bangs it wasnt bad.

Next morning (today) woke up with a sharp headache at the spot that lasted about 5 seconds then it was gone.

That sharp pain has occured about 6 more times today.

I dont have any nausea or dizziness but Im concerned because Ive never had this kindve sharp lightning pain before. Ever in my life.

Went to the ER and they asked if I was naseous, dizzy, etc. I said no. They offered to do a CAT scan but I said "no thanks" The radiation y'know.

Anyway - what do you folks mean by an "extreme, severe headache" I want to be aware of what symptom should be a concern - Im a bit confused. Thasnks
