Hi, I am 62 years old and have had headaches like this since as long as I can remember. I alway called them my cattle prod head pain. Out of no where I would get a jolt of pain in my head. When I have an attack it will last any where from a dozen and then gone to days of recurrent zaps on the side of my head maybe dozens of times a minute. My head will be so sensitive I can't comb my hair over the spot for fear of triggering another jolt and because of residual pain. With bad attacks I get nauseated after a couple of hours but it is probably just the stress and pain. This can be on either side of my head but I have never had bilateral headaches like this. It actually sounds like a zap in my ears also.
I have said if these were a constant head pain you would not be able to stand the pain. It is that intense, but that quick. No doctor has ever been able to tell me what these are and I sometimes feel they don't believe but it is real and horrible and I thank God comes and goes.
This week I am experiencing several of the attacks. I recently had a steroid shot in my hip so don't know if that triggered it. I have never found anything that helps either. I am somewhat relieved, but sorry for you all that others know exactly what I am talking about and have the same thing.
