Sir, I was wondering. I had bells palsy over 5 yrs ago. I know that symptoms can be caused from viral infection, and stress. I was put on meds it went away. But is coming back cause of stress. When referring to the web, all I get is that its caused by herpes. I have always gotten checked yearly, and my test have came back fine. Therefore if I have unprotected sex, would I be automatically given them herpes?
