Hi, thanks for that. I have been under the nuerological specialist for severe head aches for a while now. Its been quite a strange one as they are induced during orgasm and lasted between 10mins and 5 days! They were pretty horrific but they have seemed to have died down a bit now. They ran a number of tests and I also had a MRI brain scan which thankfully came back fine. They put it down to a condition where they arteries in my brain enlarge and enflame under preasure. They have given me tablets to take for six months which slow down my heart rate and general motabolism however I am not comfortable taking these.
