Shelley,
Although there are many similarities in post radiation recovery, if something different appears, do not hesitate to ask the question early. Pains will come and go, but things should ever be changing.
The doctors are checking for normal recovery, signs of recurrance and any other unusual indicators. Tell them everything, no matter how trivial. My recovery from radiation was unusually quick, but my worst week during the whole process was the week after radiation stopped. Go figure. Good luck to both of you.
