Should my surgeon pay for revisions and ulnar nerve damage post plastic surgery? (Photos)

I had a brachioplasty 11/17 and had had pain in my right arm ever since.I was diagnosed with ulnar nerve damage a few days ago. I saw the plastic surgeon for revision of my thigh and pain problems with my arm a few weeks ago. He smiled and told me that my results were "excellent" and sent me on my way. Two other plastic surgeons have since told me they can't revise the scar is to close to my ulnar nerve. I think the surgeon should pay for my ulnar repair thigh revision. Is this reasonable?
