My fiance has had a positive blood test for HSV1 but never had any symptoms. Last Wednesday he came home with what he thought was a zit on his upper lip, right where it meets the skin. We watched it for a few days and on Friday it was pretty clear it wasn't a pimple. We thought it was a cold sore so he immediately started on Abreva. He didn't have any pain, burning, tingling or itching before or during. Today, about five days after we noticed nothing has changed with these mystery bumps. They sort of look like blisters, but they aren't super red, more pink, painless, and are not oozing or weeping or forming one large open lesion. They look exactly the same as they did on Friday. We're wondering if these truly are cold sores or something else? Do cold sores always follow the same cycle and symptoms or can they sometimes not pop? Could abreva be preventing the sore from going through all the cycles?
