Scar that opens every winter
I have a scar in the middle of my bottom lip. It goes from the very bottom straight up into my mouth about a quarter of a centimeter.
I have had this scar for years. During summer, the scar is healed. However In The fall, winter, and spring, the scar opens. It isn't very painful. But it gets annoying. It will even get crusty on top but be either slimy or bloody under the crust. Is this normal? Does anyone know why it could be opening year after year?
