I tend to have trouble staying asleep and sometimes falling asleep so I move a lot changing the position of my head. I do this as much as 30 times a night but lately i've been waking up with a headache in my forehead. I've never had this before but it goes away usually after a day or two. I was wondering if it's possible that repeatedly changing positions on a pillow can cause headaches or if it's maybe from something else. Thanks for any replies.
