thanks for getting back to me. It is usually in the back of my head. I don't usually have a runny nose, not on a regular basis. It doesn't last long just some sharp pain in the back of my head and then disappears. I do have to wear glasses but i just wear my contacts.
1. You might need glasses, as any change in vision strains your eyes and can cause sharp headaches.
2. You may have sinus issues. If you constantly have a runny nose, post-nasal drip (sinus drainage down the back of your throat) or a stuffy head, these are all culprits. For me, if I get stressed and have a stuffy head I can get a migraine. No fun at all.
Wondering "where" the pains are. Behind your eyes? (sinuses) Close to your ears? Between eyes? Where at?
