Hi, for a few months now, I've been having an on-off pain in my left temple. When I lay on my right side and try to sleep, just as I am about to drop off I get a shooting pain which spreads from my temple right down neck and over the left side of my face which wakes me. When I sleep on my left side, this doesn't happen.

I often have a sore neck especially in my left side, and have to move it from side to side to 'crack' it, and sometimes gives me a headache in the back of my head. I also have a very quick spasm which occurs frequently under my left eye. Has anyone and ideas what this could be ?

I have been recently diagnosed with gastritis, and been going through quite a stressful time recently if this has any bearing.

Thanks in advance.

Ste
