Dear osteoradionecrosis: I’m not certain why you signed your post osteoradionecrosis but this is a condition that is uncommon and caused by high doses of
radiationCystitis - noninfectious
Radiation therapy involving bone. It is most common in areas of the head and neck. Regarding your surgical question, shoulder drop is a very uncommon complication of lumpectomy and lymph node dissection. You should discuss this with your surgeon. If you are not getting answers, you might want to seek an opinion from an orthopedic specialist or a neurologist who would be able to evaluate your situation and make recommendations for evaluation and treatment, if necessary.
Best wishes,
Verna
