 [ Symptoms ] herpes cold sore or angular chelitis  this thing appeared on the side of my lip that looks like a blister but is split in the middle on either side of the split there is excess skin and it hurts when i open my mouth when it was closer to healing there seemed to be a yellow crust around it i have never had a herpes cold sore before so it is going to break my heart if i have just gotten the virus it is taken about 2 weeks to heal probably because i messed with it in the beginning never noticed and small blisters though [ Disease ] do not sound like herpes simplex to me but then again i did not examine you you are correct about angular chelitis as being the most likely explanation but next time show this lesion to a medical professional herpes tends to have a cluster of small and painful blisters and may be recurrent showing up again in the same place
