I have had mouth ulcers since October of 2016. I have had three doctors in my primary care physicians office giving me everything under the sun. Then my dentist referred me to an oral surgeon. He did a biopsy on December 21st. That biopsy was negative for cancer and two other diseases of which I do not know the name but, I can get it. and the mouth ulcers absolutely do not go away. No matter what they give me. I have a huge one on the left side of my tongue and it has been there for over three weeks. It is very sensitive when I talk and when I eat and just sensitive during all my waking hours. I have used salves and magic mouthwashes and different pills. Then I went to see an Eastern Holistic Doctor who did acupuncture and gave me two sets of pills to take three times a day and each time take 5 pills each. What can I do? She said I had a problem with my spleen. I am lost and very frustrated.
