For the past three weeks or so, I've had a crack in the middle of my upper lip that will not heal
. Just about the time it starts to feel closed, I smile, and - bam - it opens up. Two or three years ago, I started developing sores that somewhat appear to be cold sores, but don't really run the course of what I know of cold sores. I never had cold sores before in my life, but, one of my sons suffers horribly with them, so, I was familiar with the what they're like.
