, as I've had very bad heartburn lately, and they said they thought it looked like oral herpes. I have had no lesions anywhere else, and my partner has never had any symptoms, so I was shocked. A blood test indicated a recent or current 'zoster' infection. Does that mean that it was shingles, or do I still have to worry about this being HSV2? If it matters, I have always been prone to canker sores & fever blisters since I was a kid (if I eat too much chocolate, tomato, have a cold, etc.). Thanks so much.
