Hi Ashelvo
I was lucky enough not to get many mouth ulcers but when I did I found vegemite really helped. I ate lots of vegemite on toast or you could put it directly on the ulcers. i think it is the salt content that helped. if you do get oral thrush fresh pineapple is great and helped me. i tried the Nilstat and the prescribed lozenges but found the pineapple more effective.
Chemo has given me a very husky voice which i find hard to project, no sore throat although I sound like I have. I had last chemo yesterday yippy!!!! so hoping to get my normal voice back sometime soon and so I can get back to singing in my choir again. :)
Good luck with your treatment, there are better days ahead.
