Barbara5524,
10 sessions is about the time side effects start kicking in!
Take a look at foods you’re eating if they have sharp edges, are too acidic. Try eating soft l, bland foods! Take a look at your tooth brush if it's too hsrd. You want one that is soft or a baby brush! Mouthwash shouldn’t be full strength. Mix sine with water and none of that green or blue stuff with alcohol.
Do you have a feeding tube? It shouldn’t be used until you need it, but it needs to be flushed. Do the mouth and neck exercises wether you have a tube or not.
Do you have any pain medication? You may need some, and don’t wait to get it until it’s needed! Theagic mouthwash has 20 other names, but is pretty good to numb the mouth. They say not before eating lol, but that’s what slot of people use to eat! Just talk you your doctor as it’s a prescription rinse.
Things may get more difficult From now on until several weeks after treatment, and some beyond. If you have any questions, ask here and if course with your doctors.
Good luck
