What Causes Blisters On The Lips?

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

Hi..
Thanks for the query..

First of all make sure that the person with whom you shared the drink was actually HSV 1 positive and was having a breakout that time..
Secondly the HSV 1 sores are in the form of clusters of fluid filled blisters, so it should be checked that you have a similar presentation..
So once you are confirmed with these then it you need to proceed for investigations like Viral culture, antigen antibody reaction etc..
Get examined by an Infectious medicine specialist so that you can be advised accordingly..
As of now if you are doubtful avoid close contact with other to avoid transmission of infection if at all it is present..
If viral infection is ruled out a long term anti-viral therapy with antiviral drugs like Acyclovir, Valacyclovir, Famicyclovir can be advised both oral intake and topical application.

Hope this helps..

Regards..
