Hello, my DD had this about 12 months ago, her whole mouth, lips, tongue, gums, everything ulcerated. Fortunately I have a dietician friend who was able to advise me as she stopped eating for several days (big fright). She recommended making up a fortified protein drink by adding skim milk powder to regular milk, which you can then use to blend mashed potatoes & pumpkin, scrambled eggs, etc, which are soft and bland. You can add it to canned chicken soup etc as well.

Just as an aside, in DD's case we had four different drs tell us it was 4 different things until the viral pathology came back two weeks later and the only thing active in her system was chicken pox virus (!)

Amy, I hope you are feeling better soon and get on top of this - rest up and drink plenty of fluids and let your friends run around after you when you can!
