@harleytiger That stiff neck stuff just seems to hang on for years no matter what I did to try and ease it some. A yawn or specifically a sneeze would sometimes bring me to my knees nearly. It has gone away completely but I am now twenty-five years out of radiation. I guess the solution along with time is to keep stretching it.
I hope you don't have the many lasting side effects I have had such as osteoradionecroisis and having my jaw rebuilt five years ago. That was fun. At least the recovery was much faster. My original radiation oncologist had me as his first head and neck patient. Someone had to be first and at the time I didn't know better to ask. As a result, he learned and I paid the price. Water under the bridge. I am still here and doing fine. I want you to enjoy the years to come like me. By this time next year you should be doing much better. You might even go an entire day without remembering you had cancer.
