@kamrin I had one lymph node affected on each side. So bilateral radiation was a definite for me. I'm not sure about the worst side effect. I felt exhausted and generally unwell after the third week. I think that was likely the combination of the two treatments. My mucositis was mild to moderate, but my pain was tolerable. I did not use opiates. I drank very high calorie boost throughout and did not have a feeding tube. The worst effects of the radiation came the 2 weeks after treatment ended. That was my worst pain. But it passed quickly after that.
