I have lots of mouth ulcers that started out with just a few, now there are a lot of them. My doctor gave me a rx for "Magic Mouthwash" It is helping some, however, more ulcers are appearing. She also gave me a rx for an antibiotic as I have a very bad sinus infection. I s there anything else that I can try. Because of the sores I don't have the desire to eat even after using the mouthwash. I also have non insulin use Type II DM.
