Hi Dr, I feel constant pressure at one spot in the head on the left side of head diagonal to the top of the ear. On sleeping, the pressure is felt in the entire head. I had consulted with the GP, who gave me pain killers and sleep medicines probably, it worked for a day, but today again I am unable to get relief. BP is normal. The pressure travels to the front and face occasionally However, I am feeling constant pressure. I also suspect a pinch nerve in the back of my neck. Can a pinched/pulled nerve cause this pressure? what can I do for relief. Please let me know. Thanks
