I recently shared a drink with someone who may be hsv1 positive. I was on vacation in a remote location so I didn't practice as good oral hygene as I should of and felt like my lips and gums were resting on plaque. I also bit my lip and cheek the same night. A couple of days later I had what I believe to be canker sores on my lip and cheek. I went to a health center because my doctor can't see me until next week and she said it is a 50/50 chance it's herpes or a cold sore but wouldn't do a swab because the clinic doesn't determine them to be stds. It was never a blister and only appeared on the inside of my lip. Any feed back would be greatly appreciated as I still have a week to see my doctor
