I have had M.S. for about 39 years now. This last year or so my trigeminal . If y nerve has been acting up. I have done a lot of thinking on this. It seems like when I am stressed. Drop in barometric pressure below 100 kpa and strong winds cause this nerve to act up causing lot of pain in my face when I talk shave and brush my teeth. Has anybody out have had this experience. If yoI would like to hear from you
