Hi Chandana
I am 62 and 10 month post radiotherapy for tonsil cancer. I too had ulcers and a radiation burn the full length of my tongue. I was prescribed gelclair which did alleviate some of the pain.i am in the UK so my treatment May have been slightly different. Once treatment finishes just remember the hard work really does start as we all recover at different rates. I found it was bettervto have an idea of what was going to be in front of me as opposed to blindly not knowing.

Hope this helps
Regards

Hazel
