Just had fundoplication surgery and have very bad crepitus and severe pain. Advice?

Got out of surgery 1pm yesterday. Woke up in severe pain and was given zofran and morphine 2mg. I have crepitus all across my chest and face. It feels like I have rice crispies under my skin and crackles when I apply pressure. My chest feels so heavy and I hurt everywhere. I can barely stand up to go to the bathroom. I'm now on a 4mg morphine drip and it just barely takes the pain away and wears off after just 3 hours. Did you guys have this kind of pain?. I'm going to get discharged today and I'm scared. The nurses said they've never seen crepitus so bad in a face before but surgeon said it's fine and will go away. Please give me some advice or encouragement guys. No family here to cry to so here I am

I was in a lot of pain when I came out of surgery, but they pumped me full of dilaudid, zofran, toradol, and steroids. Sent me home with OxyContin. My real pain started several weeks later (except for shoulder pain, nothing but walking helped that, it faded after a few weeks but I still get the occasional twinge)
