I think it is important to remember that everyone is different, and our treatments may differ some. I did work all through treatment, but I only had radiation no chemo. I also talk for a living (mental health therapist). I had red, rosy cheeks but no blisters or burns. The inside of my mouth burned and hurt. I would use the Mary's Magic Potion when I needed quick relief. I took pain meds as needed, saved the strong stuff for bedtime. The worst pain was attempts at eating. I became a fan of milk. I found the if I drank milk when I ate it coated my mouth and helped. I definately could not eat anything with any spice or rough texture, so plan on a lot of milkshakes! Remember the radiation continues to work even after treatment ends. Some of my worst days were in the two to three weeks following treatment. It does get better and soon becomes a vague nightmare.
