Hi I am wondering if this is any thing to worry about but I have started getting headaches again ( I had severe ones for some months prior to PMR ) and also I have been noticing for a while that I seem to have a stiff jaw. I feel like I need to wriggle it from side to side to loosen it. I do seem to notice it when I eat but I can't say there is any pain on eating just a stiffness and it is there alot of the time. I dont have any pain either when brushing my hair etc just an all over headache. Any ideas?
