Where are the sharp pains located exactly?

Sounds like allergies... try an allergy medication with pseudoephedrine (e.g. Claritin-D or the Target generic). It totally stopped my boyfriend's migraines and ice pick headaches, so I'm trying to spread the word.

since, I think, allergies have passed, the pains are much, much less fequent.

I experience the same pain but I do not have sinus or allergy problem It has been 5 days now, I felt sharp prickly pain in my left brain/head. It started when my neck hurts and kinda swell. Last year, I fell in my bathroom and had a concussion. Only x-ray was done and I had to consume tons of pills. Doc said not major injury, Hiwever eversince the incident, I alwaya get neck pain. I was a perfectly healthy person before the fall. Is this related to pain in my left head? Pls help
