I get sore spots on my scalp that come and go as my flares/tightness come and go.
I know some would get really bad headaches and one -she just re joined recently Starla - she would have very bad face pains if I remember right.

in our stickys there are some good anatomy links in post #1 {long list scroll down to find the anatomy section} maybe you could track down the nerve or muscles that could be causing the trouble.

when the head pain is the worst - are you feeling tight in your neck or upper back muscles?
