Jenny R you're not alone. This sharp stabbing pain woke be up out of bed this morning. For me, the pain seems to start on the right side near the base of my skull where all the muscles insert. Then is seems to end up some where behind my right eye. All of this happens within seconds, but it's very scary & annoying. It seems to have started yesterday & the funny thing is that it didn't bother me at all while I was working out. I haven't gone to the doctor yet about it since it just started, but I've had the pain before years ago & remember going to the ER. They gave me a catscan & told me that my head was fine. The pain just seemed to go away on it's own. It would be nice to know what the problem is.
Jenny, you might want to do a search for Occipital Neuralgia. I had pain nonstop for 4 months before someone on this board mentioned Trigeminal Neuralgia, and when I researched that it led me to Occipital Neuralgia. It's worth a try!
