Why is my neck extremely red 8 months after my neck lift surgery and feels like it's on fire? (Photo)

I had a Platysmaplasty neck lift 8 months ago. The Doctor did perform liposuction as well. The skin from my jaw down, on both sides, to my collar bone is deep purple and very red. I look like I have extreme rope burn and it feels like it's on fire all the time. I visit my doctor for check ups but he shakes his head and says he doesn't understand why this has happened. Another note: 4 months after surgery, I developed inflamed veins in which he had to drain 3 times. Please advise. Thank you.
