I keep getting disregarded by doctors that ive tried to show this to or bring attention to it. it seems like its brushed off as nothing more than a canker sore. its been there for like two months its painful. can i show someone a picture of it?

No pictures here: This forum is for general medical/dental questions, not for a specific diagnosis for your condition. Two months is a long time. I suggest you make an appointment with a local oral surgeon, a dental specialist for these types of issues. Tests may be needed, even a biopsy, to determine what is causing this lesion. Then treatment can be implemented.

Needs attention: Any oral lesion that does not completely self heal in 2 weeks deserves further attention. Canker sore should be healed by now. Please see a specialist Oral Surgeon or a specialist Oral Pathologist for an evaluation.
