try a asprin a day for a week it may help . just one asprin a day though dont over do it cause it can thin out blood too much , it should help and it should help you keep from
a heart attach and or stroke.
Coming from someone who has had an anuerysm I would say it sounds like TMJ/ anxiety, however if your headaches get severe or you start noticing troubles with movement or speech along with the headache, then I would consider looking into it further.
yes dont let it go. get help asap
