They start small and over about a week they get bigger then shrink again. They are sore, sometimes so sore that I can't eat. Nothing like an ulcer to look at. The area becomes very flat, red and smooth and sometimes cracks too. The one I have right now is in the centre of my tongue, but I have had them on the edge before which is real agony.
Does anybody get similar? Or know what it might be?
TIA.
