<s>[INST] For 7-8 months I've had ulcers come on my tongue off and on as soon as they would go away some more would come on in another area on my tongue. It got to where some time it was very hard to eat or swallow. It also affected my ear by hurting. Then I noticed blisters (one or two small) would appear at a time. I'm going to a ENT doctor now to see what is causing this problem. He has ruled out cancer. It seems like I can't get rid of these or be told what I need to do to treat it or what can be done to make it all go away and stay away. Can you help me? [/INST] Hi.Thanks for the query..If the ulcers come and go that means if the ulcers appear but they resolve completely over the time then it is not cancerous because cancerous ulcers does not heal and are persistent..So my suggestion is to consult an Oral Surgeon and get examined and the first thing that should be done is Biopsy if ulcers are considered cancerous..Further treatment can be decided accordingly..For now you can apply a  steroid oral paste over it and along with it gargle with 1:1 solution of benadryl and milk of magnesia..Do warm saline gargles..Take Vitamin B complex supplements..Hope this helps..Regards.. </s>
