Hi John. The radiation continues on even after treatments stop. My husband John unfortunately didn't notice any improvements the first month after treatments ended. Around 6 weeks out of treatment the mucus started to get better. By around month 2 the mucus was all but gone. John basically didn't try talking for a month because the mucus was so thick it would make him gag and throw up. He was on both Zofran and Compazine for the nausea during the first month after treatments ended. I know it is hard to be patient but only time will help heal the mouth sores, throat and tongue. You are through the worst and better days are ahead. Hang in there!
