Years ago I started getting crawly feelings on the left side of my head and face. Through the years it turned into constant pressure radiating to the left side of my neck. I could often feel the muscles pull on the left side of my neck. I had bad teeth so I thought it might be TMJ, so I had my bottom teeth pulled, and I got top dentures.. Unfortunately the dentures were very uncomfortable so I rarely wear them. I also had a sinus operation, and that did nothing for me. I have lived with this chronic condition for years. Recently the pressure in my head has become unbearable, as when I lay down and try to relax it throbs, and the pressure gets worse.
