I get "pulse" type head pain, it usually is on the back of the head, but has occured at times at the side around my ear. It feels like someone is pressing a button / buzzer. The pain is like a pin point sharp pulse that lasts for approx 1 sec and then will go away for some 30 seconds before returning. This can continue for days. Some times up to three days at a time. It feels like an electric burning sensation and sometimes I feel like I have to close my eyes will the pulse is on. I also note that my scalp around the area is very sensitive when this occurs. It does not go away at night when I try to sleep, it keeps me awake. I have been to the doctor, but usually after it has gone away. I have had nerological tests, with probes attached to my head and and flashing lights but quite frankly I don't think they know what they were looking for. Nothing seems to help, not 222's, asprin, tylonol etc.. Any ideas what this can be ????
