I get headaches in the back of my head that only will last a few seconds at a time. I am 32 and otherwise healthy. I can't figure this out. I have had a receny physical, bloodwork and an ekg all coming back perfectly normal. I was once told i was having some tension headaches, but this is very different. The pain only lasts seconds and comes and goes, usually on the back top left side of my head. Does anyone else have this problem or know what might be going on??
