...the corner of my mouth is cracked, a little manky, and appears to be bleeding a little. It has been like this since just before Christmas. I have been sporadically using Blistex on it, but keep forgetting to take it to places with me, and i eat what i would imagine is a reasonably well balanced diet.
What i want to know is how do i make this stop? Am i lacking in some essential vitamin or other?
Your advice will be gratefully accepted, and if it works, i will reward you with a great big kiss when my mouth is all better.
