Didn't your doctor give you any POST surgery medications? I wish you had talked to him prior to surgery about this. Give him a call and tell him about the terrible pain you're in -- tell him you NEED something for this pain!! You can go on like this -- how in the world do you sleep?
Obviously whatever meds you have aren't touching this, so ask him to Rx you something to help. I wish you the very best. God bless & take care. Hugs, Lee
