I had a hole in my tongue for a while (this was after rads though) I thought for sure the cancer had returned - I did everything and it didn't heal - my ENT said he thought it was an ulcer gave me oracort - following the directions (use it 2x daily) didn't work after two weeks I was beginning to freak, but I also didn't want them bio paying it unless absolutely necessary - frustrated, I started washing my mouth after each meal and then applying it, and applying it before bed ..l within two weeks it was gone.

Sometimes if it's deep enough it can be VERY painful, and sometimes an ulcer is just an ulcer, here's hoping this is the case with you. Push to get the biopsy ASAP!!!
