[|Human|] I have an unusual cold sore or canker sore on the underside of my tongue. I have a history of renal cell carcinoma so a biopsy was done. The biopsy came back stating inflammation. I have had this at least 2 months and is very painful and is getting larger. I went to my nurse practioner and she prescribed a miracle mouthwash. This only numbs my mouth for a few minutes and the sore isnt improving any---only getting larger. She says I need to see an oral surgeon. What is your opinion? To me it looks like a big ringworm! Its in the shape of a circle with a round edge and red on the inside.
[|AI|]  Hello, The symptoms can be due to causes other than canker sores or like bulbous pemphigoid. The explanation is not looking like a canker sore. Yes, it is correct to advise that you need to consult an oral surgeon and get evaluated. A clinical examination, CBC and a repeat biopsy can be done for confirmation. Also, continue gargling with magic mouthwash, apply chlorohexidine gel and a steroid gel-like Analog in Or abase and take vitamin B complex supplements. Hope I have answered your query. Let me know if I can assist you further.
