The thick mucus, sometimes called rope mucus, generally lasts 2-3 weeks after the completion of radiation. Sleeping on an incline may help, brushing, rinsing often, rinsing with seltzer water, tea, pineapple juice and or papaya juice, taking Robotusm or mucenex, drinking plenty of liquids. Using a Waterpic to get any gunk out in hard to reach areas, using sponge type tooth brushes on sticks to brush arounf the gums, back teeth area. I liked to have egg drop soup, which also helped clear my throat.

Good luck.
