Scar Tissue After Neck Sculpting? (photo)

I had a neck sculpting on September 5th of this year. I went back to my doctor because I noticed that I am more swollen now than I was 4 weeks ago. My doc said I had developed some scar tissue in my neck, so he injected me with mixture steroids and chemo to break up scar the scar tissue. Then they did some ultra sound at the site. I had never heard of the chemo/steroid mix, what is the success rate for this? It's been 2 weeks, and I don't see much improvement, will this be permanent? Update: Posted here.
