I've been unwell with a sore throat / cough type bug for a couple of weeks and almost out of the blue the skin at the corners of my mouth has cracked and split on both sides, it's extremely sore. My lips look a bit swollen and feel dry and tight, they aren't chapped as such but around the edge of my lips on my face feels sandpaper. It's horrible and is so uncomfortable.
I've been covering it in lanolips.
Does anyone know what this is or how I can heal it up quickly?
