lumpectomy site issues

I was just wondering if anyone had this problem and what was done to correct it. Quick history:
I had my lumpectomy over a year ago. It seems like it never fully healed, always sore and swollen with fluid. In March I noticed a lump just above the incision site. Rad Onc. had me take antibiotics twice, thinking it was infection. Didn't help. Surgeon did biopsy and said it was scar tissue and radiation damage. She said it would heal but instead the lump became a blister on my skin and the whole top half of the breast was red and swollen. In June the incision split open and fluid began literally pouring out. Surgeon drained it and wrapped me. She said she does not want to make any more incisions now because the radiation damage is making it hard for me to heal. Fluid has been constantly dripping or flowing ever since. Couple of days ago the blister became infected and now has disgusting stuff coming out. So I have been having to wear bandages day and night for weeks now. It hurts when I change positions in bed , when I lift my arm, just about any movement I make. I have an apt with the surgeon tomorrow but I have no idea what she will be able to do for me. Anyone had anything like this or have any suggestions?
