I have had headaches previously. Over the past yr and a half, i have had what i call "brain pain". Pains in my head(sometimes both sides). I have no dizziness,weakness,blurred vision or anything else. Had two dilated and clear eye exams over this time. Does not stop me from any activities. Does throb at times also. Scared to death of a brain tumor. I also have constant runny or stuffy nose and prone to sinus problems. Please Help!!!
