My mom is about 15 sittings of IMRT (SCC base of tongue) down, and there is significant discolouration of the skin both sides of the neck. How long does it take for the colour to come back? Does it ever come back fully?

Also, she finds that as the IMRT goes on, there're mouth sores that are becoming quite painful, and coming in the way of food. How do you treat these sores? Is Iodine mouthwash mixed with water, as a gargle, good for it? What have you used to treat this?
