Keep knocking those weeks out! After week two most side effects start to kick in, but knowing that puts you ahead of the game, and should have everything lined up to help, like the neck cream the radiologist suggested, mouth rinses, oral care, pain meds, etc. The last two weeks will be the hardest, up until two weeks after with the rope mucus. The sore throat is probably the effects of radiation, also chemo causes basically the same ailments as does radiation, only sooner after infusion, but tell your doctor about it, and infections, common with treatment, can get out of control. if not treated properly. Ate you doing the salted warm water, baking soda rinse?

Good luck.
