Throat ulcers

hello all

finished my RT eleven months back and all seemed  pretty good, well as good as my Onc said it would be.

recently though I habe ulcers on the back of my throat and nasty so and sos they are too been there three months now.

odd thing is no medical cure apparently, cancer yes ulcers nope!

wondering if anyone else has experience of the blighters?

thx
