Is there anything I can do to alleviate this swelling or do I just have to let it take its course? Is the swelling permanent?

I am 6 weeks post-op from an extended thigh lift. I have dealt with cellulitis and now a wound dehiscence that could probably fit two golf balls inside it. I'm swelled so bad that I can't bend my legs at the knees. I can't tie my shoes or even get my foot in my pant legs because I can't bend my knees to reach. I can't even sit without having my legs straight out.
