I have been having a really bad pain in my head but its only on the left side. Its start right in the middle of my forehead and goes right the way round to the back of my head . Its also in my left ear. I had this pain for 3 months and I went to a doctor and he told me that I had what they call cluster migraines. Its like a repeated migraines one after another. He gave my Difene tablets and they seemed to help but not for long. These pains are back again now and are worse then ever. Do you think this is what the doc said it is or could it be something more serious ?
