<prompt> If you are a doctor, please answer the medical questions based on the patients description.Good morning. I was diagnosed yesterday with shingles . It is all along my left temple into my scalp and left ear, with one patch on my cheek, two on my chin and one on my bottom lip. I have terrible ear, jaw and teeth pain, to the point that when I went to the dentist on Monday before the rash broke out she told me I needed a root canal this was for my bottom front tooth, which she performed. Now I have horrible pain in my left back tooth same side as the rash. Can this be from the shingles? Thank you so much.  <response>: Dear Maureen, Only a dentist can examine let you know whether there is some decay or gum problem with your back teeth. Mostly the pain must be due to Shingles Herpes Zoster- a virus infection. Which has affected the nerve supplying to your left side. This Shingles generally happens when your immunity is low you are under stress. Good nutrition rest is the key along with Anti-viral therapy. Get well soon.
