i am so glad to know i'm not losing my mind. i have had these sharp, intense but brief pains in the back of my head for months. it happens when i move my head in a certain way, cough, sneeze, etc. it is a horrible pressure and stabbing pain that shoots from bottom to top of head, right up the center. lasts for about 10-15 seconds. but those seconds are the most painful i've ever had. if i'm sitting on the sofa and push my head hard into the back of sofa it seems to relieve some of the pain. i go to the va and the first time i mentioned this to my doctor, she said it was probably from my high blood pressure. a few months later with a new doctor, i was told it was a migraine. i've never had a migraine, in fact i hardly ever get headaches. she gave me a new blood pressure med that helps with migraines...it hasn't done a thing. just another pill to take. my blood pressure isn't that bad! i have a follow up appt in a couple weeks, but as a smoker, i keep thinking i have a brain tumor or something horrible like that. it is very scarey and it hurts so bad and i get lightheaded. when the sharp pain subsides, i'm left with a dull ache. let me know what you all find out and i will do the same. thanks
