Sorry to hear that you are in pain. I am not sure how many lymph nodes you had taken out. When I had my lumpectomy and sentinel node biopsy, I could definitely feel more pain after about 2 weeks - not where my scar was but in part of my upper arm and top of my breast. I think it is probably where the nerves are. It does get better.
Since then I have had the rest of my lymph nodes removed and again about 2 weeks later, the pain was in my upper arm.
