I recently began getting cuts on my lower lip. They seems to come from nowhere, this has happened three times in the past two weeks. In addition to small red rashes appeared under my lower lip after receiving a wound to the head. No blistering or pain came with the rashes. I was in a relation ship with a girl who got cold sore about four months ago. I never noticed cold sores on her while we were intimate and never noticed anything on me until about three months ago. I just wanted to know if it was possible for HSV-1 to react without the typical cold sore symptoms and just cause cuts on my lip. The cuts usually heal in a day or two and are some times red. I am also in the sun working most of the day so could this be the cause.
