Mark and Joannie,
You might not hear of lingering pain because not everyone has it.
I had a modified radical neck dissection, then radiation to my entire neck, as they couldn't find the primary. I've been out of treatment for 16 months. I only ever took one pain pill for it, and that was in the hospital at the nurse's insistence.
I don't really have any pain as a result of either the surgery or the radiation. The left side of my neck is still partly numb from the incision upward, due to severed nerves, and I do have a lot of tightness on that side, which is worse at some times than others.
My RO gave me instructions to do "gentle massage" to the area myself several times a day to prevent fibrosis and lymphedema. I was pretty good about doing it for the first six months or so, but rarely do anymore.
Have you explained this to your doctors? You shouldn't have to deal with so much pain for so long.
Best of luck to you with this.
Susan
