I've been really run down recently and have developed several ulcers on my tongue and mouth. Incredibly painful and uncomfortable. Anyway, I've been treating them with over the counter stuff. It's been 14 days now and they are not getting better. In fact, I've developed two brand new ones in the last week! I've got a GP appointment in Thursday but was just wondering if anybody else had suffered from these. I can't help thinking that my diabetes is slowing the healing but I am getting very fed up of this now!!
