[|Human|] Have large white area on right side of my palatoglossal arch. Started after a sinus infection where I had a persistent mostly dry cough through the night for several nights. I do get cancer sores in my mouth from time to time, but never had one back here. The excruciating pain has subsided, but the area is still tender and there seems to be a small missing area of the arch now.
[|AI|]  Thanks for your question on Chat Doctor. In my opinion you should definitely get done biopsy of that whitish lesion. Since you are having recurrent malignant oral lesion, your present lesion has high possibility of malignant too. So biopsy is must. Take multivitamins having zinc and folate for better healing of oral ulcers due to malignancy. Also quit habit of smoking if you have. And consult ENT Surgeon for further management.
