hi ive been having pains in my head on and off for about ten years.Its like someone is sqezzing my brain.Sometimes i get mild confusion with them.Something as simple as swallowing can bring it on.ive had brain scans but everythings fine. Sometimes the pain moves around.it last for a week.When it starts its very severe and when it goes away its like something has is being drained from my brain.I have also noticed when its gone i have terrable inner ear pressure .I also have tinnitus dont know if their linked.
