Congratulations for being a survivor! With that comes the life long trial of always being observant of your body and being concerned about minor aches and pains that you now recognize could be signs of serious medical issues such as cancer recurrence. Within those constraints, you are challenged to lead a "normal" life, and so your concerns are very normal. The shortest answer is that, while most aches and pains are likely related to your previous treatments and the healing process, it is impossible for me to know and so you must speak with your doctor
. He or she will know you quite well after what you have been through together, and so it is important to discuss these concerns with him or her. Radiation and surgery
both have prolonged effects on the remaining lymph nodes and muscles in the area. Some of these changes may persist for the rest of your life, and will become routine and expected to you. For the time being, however, it is important to discuss new findings with your doctor to make sure that you aren't missing something important that could be an early sign of something that needs to be treated. Again, please speak with your doctor.
