I'm in the same boat. My 35th radiation treatment was on sept. 10th and the pain is showing no sign of letting up. My feeding tube came out in my sleep around the 8th but i was eating mostly soft food so I told them no sense putting one back in, so they agreed at the time, but now it hurts so much that I can't even gargle or move my tongue at all. Looking like another tube is in my near future since I'm having a hard time eating enough to maintain weight. I had to have my bottom teeth removed because they were worried about osteonecrosis, where if they have to pull it out after radiation, the bone will never heal, causing potentially deadly infection.
