Update: I saw the Otolaryngologist today. The same doctor who performed my dad's surgeries. He found what he suspects is oral lichens planus on both of my cheeks, and the base of my tongue.
(I didn't see it on BOT, learning to look better)
He referred me to his dermatologist for biopsy with an asap text message, but told me not to lose sleep over it. I hope the resident who was working with him and examined me just before my dads doctor was paying attention, because he said he didn't see anything wrong. Have a dull ache in left bottom jaw, hope it's nothing. His nurse was very interested in sharing the avacodo finding, she asked me to fax it to her so she can share it with her patients, she was very kind and caring and wants to especially share it with her radiation patients.
Will update again when I've had the biopsy.
