I've been experiencing neck and pain in the back of my head for the past few weeks. Its not very intense head pain but very uncomfortable. The neck pain is primarily located at the top of my neck. Its not all the time, every day. It just comes in waves. I had a sinus infection about three weeks ago along with a virus so I dont know if they could be related. Does anyone know what this might be? It comes on a lot when I lay down, or prop my head up on a pillow i'm only 18 so I feel like this is very unusual.
