Been having a lot of pain in the back of my head and upper neck. The pain used to be every now and then but is becoming more frequent with really bad ear pain, I'm been more forgetful and feel off balance. I had a neck MRI which showed elongated cerebellum and something about T1 and T2. Brain MRI said normal. Anyone have an idea because I'm lost. I'm also only 23 years old if that matters. Help?
