After 18 radiation treatments I had severe inflamation, pain and that lovely shade of red skin. Stage III, 10 positive lymph nodes, masectomy, 8 treatments of chemotherapy and 37 treatments of radiation. Each time you get the treatment it gets worse since the effect is cummulative. If available have the Doctor prescribe Silver Sulfadiazine Cream 1%, this cream is great, it alleviates the pain, cools the area and you will see improvement. It is usually prescribed for burn patients.
