Painful Lumps/ Knots After Upper Arm Lipo, What to Do?

Day 10. I wore Ace bandages for a week then my doctor told me I didn't need them. When I was wearing them they would create deep indents around my arm and the tissue that was swollen would become hard rings. I'm developing hard knots/ lumps that hurt so bAd. Should i be massaging, wearing some sort of garmet and if so what do you prefer and is it okay to use the cream icyhot to help with pain? Can i use heat or ice And what will help smooth these knots out? could these knots be withon my muscle?
