Hi Stoj, Glad to hear your in Texas, I live in Houston and i too, have SCC and had my cervical lymphnode removed. I am going through radiation right now, i have completed my 15th day, So if i can help in anyway, please let me know. As far as the sore in your mouth, try going to a health food store and getting "DGL" (deglycyrrhizinated licorice root) I crush them (tablet) and add just a little bit of water, (make a paste) then i put them on my sores and they are gone within 1 to 2 days! Put the paste on the sores at least 3 to 4 times a day. If you like Licorice then it wont taste bad, but if you dont, well it gets rid of them and fast! Hope that helps you. Anything else you need just let me know. Have a great day, and god bless.
