I have had a muscle twitch/spasm on the left side of my face (lower mouth/jaw area) for almost two months. It comes and goes, but I have tried so many things to get rid of it (changes in diet, exercise, vitamin supplements, more sleep, etc.) Any other suggestions? Could it be related to anxiety and/or tension? I do get migraines and thought maybe it could be due to blood vessels pressing on a nerve or something?
