5 weeks post op. Pain after breast reduction. Nerve damage or too much tension from internal sutures? Is this permanent? (Photo)

No drains were placed. At 2wks I had lots of tension, blisters & necrosis on 1 breast. Breast now has a painful burning sensation at the base of the T incision when I touch, stand straight or lay flat. I can palpate 2 painful bands on my abdomin that connect to the necrosis areas. Dr. injected a steroid into the area & I've felt little relief so far. He says nerves could be scarred. Is this fixable? Are internal sutures causing the burning tension? I'll mark where the painful bands are in pic.
