Just started 3rd week IMRT. Boom! sudden onsit of side effects, in 24hrs. I can handle the thick sputum, the tube feedings, loss of voice, difficulty or inability to swallow. But sudden onset of pain is getting to me. Viscous Xylocain doesn't touch it. Feels like hot poker in throat full time and then worse when I attempt to swallow. Any suggestions, please. Edd
