Hello, my son who is 6 years old has been suffering from head aches on the very top of his head. He has been having them on and off for a little over a year. He screams in pain and I can not get him to stop for about 30 minutes. He has had partical paralysis during one of his episodes. I have been to the doctors, who have done CT scans, EEGs, and a neurologist examination, but still have no answer. The possibility is migraines. My question is do migraines only last for 30 minutes and are they that painful that the child is screaming and crying in pain? No matter what I do during these episodes he does not respond until after the 30 minutes has passed. Do you have any suggestions?
