*POSSIBLE TRIGGERS: My period ending might explain the headache, but I don't understand this jaw pain.
** Pain started out right on top of my head, and it felt like a lot of pressure again. Then it spread to my temple, but was more intense there. It was in my temples, down into my jaw. It progressively got worse as the evening went on. I gave it a 7 by 9:00, which is when the nausea started and when I got sick of it and finally took something (that didn't help all that much).
