After lumpectomy, lymph node surgery and radiation therapy, I have stabbing pain in lower back?
I am a 49 year old female. Last December I was diagnosed Stage II Breast cancer, they found a micro- metastases in my lymph node on the affected side. I had lumpectomy and lymph node surgery in January, followed by 8 weeks of radiation, no chemotherapy. Since about April I have been experiencing a stabbing pain in my lower back, the exact same spot each time. It only lasts a few seconds and dissipates. But it recurs often, several times a day. This morning alone is has been occurring several times per hour. My medical oncologist thinks it must be muscular. is it possible to experience nerve damage in my back from lymph node surgery?
