Dh periodically get these things on his lips but they don’t look like a typical cold sore. It starts as what looks like a spot/bump usually on the edge of his bottom lip, but then cracks quite soon and becomes more of a cut/wound. Round in shape but it just doesn’t look like a cluster of blisters which is what cold sores usually look like. I’m always a bit wary of contact with him when he has one but don’t know if I’m being OTT. Does anyone else present with cold sores like this?
