Before I run to the emergency room or to my doctor's office I am wondering if someone has experienced what I am having a problem with. It's not a headache, it's a head ache and its on the back left side of my head and its traveling along to my neck. Its also starting to travel across the top of my head, very tender to touch any area affected. I do have MS so I'm thinking it might be MS related. I have doctor appointments all in September, my routine 3.6 months checkups but I don't think I can wait that long or if there is some simple explanation. It feels like when you make a quick turn of your neck and you get that tingling neck pain thats lasts a few seconds, only mine is non-stop and spreading.
