My tummy tuck was today! I'm pretty dang sore in my muscles. Prefer to just not move but I need to. I haven't looked at anything yet. I go back tomorrow, I have two drains and no catheter. Does anyone know about this thing I'm supposed to blow air in or out? My husband didn't pay attention at all. I swear it was suck I but it does nothing. I've never seen it mentioned.Thanks
