Recently (past 2-3 months) i've been getting extremely sharp pain shooting through my head, usually top left or temple. It kinda feels like a cramp, but i don't think it's possible for a brain to cramp. it happens every couple of days, and it's really incapacitating when it happens. sometimes it happens more than once a day.

I was researching, and stumbled upon a concept called 'icepick headaches'. does anyone know if i might have this or not? or could enlighten me or what exactly is wrong with me?

Oh, and it started not long after i ran into someone full speed with my neck half tilted while playing field hockey. my neck was quite painful for about 72 hours and still aches slightly when i tilt it backwards too far.
