So, you know when you have a knot in your neck & you can push on it & feel it's exact location & it hurst & feels like it needs Kneeding/ like massaged? Anyone ever have this on one side so high up that its on the back of their head??? I can push right on it & it is sore, and I showed my husband & he said it's where your spinal chord meets your head. Anyone else get this??? It started out as a painful knot-feeling in my neck (lower than it is now) about a week ago & now it's way up on the back of my head-- and only on one side (oddly on the side that's less affected by MS). Should I be concerned, or is this just another transient pain that cones & goes & means nothing significant?
