I didnt want you to think that you are alone. Although I have not had this paticular symptom.....I also get weird feelings. Is your cheek swollen at all? Could it be a tooth? Do you have sinus problems? It could be TMJ. Can you massage the area inside the mouth and out? Have you tried heat/ice?
Have you changed anything in your life?

Take a deep breath. It could just be one of those strange things that happens. Keep an eye on it, when its happening etc. But dont let it consume your life.

Good luck!!!!
