Quite extreme choking feeling after neck lift: exercises, or even surgical intervention?

Choking from tightness across neck after posterior platysmaplasty and lipo. I am six weeks post. I want to say that this is not a minor feeling, but actually nearly unbearable in the evenings. It is there all day, least in early afternoon, but nearly unbearable otherwise. Ultra sound therapy made it markedly worse beginning hours after, and choking feeling continues to be difficult since. PS says ibuprofen. Are there exercises, or even surgical intervention? I need to be able to work and sleep.
