Question: Three years ago after kissing a female friend I felt like I was getting my first cold sore. It was similar to what I have read on the internet. I felt a tingling on my lip and a red spot developed. I felt a strange discomfort around the area. However, it never came to a head nor did it drain. The red spot never really went away either. There is still a faded red spot on my lip from that incident. Since then I got a couple more red spots develop on my lip. The second one did not tingle but it was uncomfortable around the area. I recently got another red spot that start similar to a pimple but it never went away. This time there was no pain or discomfort associated with it. I have been tested for herpes 1 and 2 on more than one occasion and the tests have always been negative. Do you have an idea as to what this could be and if there is a medication that would take away the red spots on my lips? I don't think that other people notice them but they are obvious to me.

I am submitting a photo. The lesions are faint and do not show up well on the photo. However, the most recent one is fairly visible and is identified.
