This patient support community is for discussions relating to breast cancer, biopsy, genetics, chemotherapy, hormone therapy, lumps, lumpectomy, lymph node dissection, lymphedema, mammograms, mastectomy, radiation therapy, reconstruction, and self exams.
Knowing your previous history of breast cancer and breast surgery, these symptoms may be related to some disruption of lymphatics and blood drainage from the involved arm. Inadequate drainage can indeed cause this pain and may even progress to some form of lymphedema.
Another possibility is bone involvement by the cancer cells, the pain of which can be progressive. It should be discussed with your doctors regarding a possible bone scan or PET scan to assess if there are new or existing lesions in these areas.
Regards and God bless.
Thanks again for all your help.
