I think she's got a prankster for a doc. Make sure he doesn't have his phone recording when she does it. She doesn't want to be on his YouTube "Patients I Made Fart Before Sending Them Home" channel or "I've got just enough gas to get home". They never asked me to fart before leaving but I do recall them asking me stop when I arrived. I get to a hospital, I feel all bodily functions are game and expected. If not there, where?
Gip, I had one repaired in 2009 and the most unpleasant part of it was that surgical tape they had over the incision. It restricted movement which really wasn't all that bad since I wasn't supposed to Bossa Nova for several weeks. Just tell her to take it slow n easy and be a good nurse to her. And stop making her tote that barge and lift that bale. Move to the country and work your woman like a mule. City boys need training on how to live the country life.
Now, as a parting gift from my hip and exacerbated by the gall bladder removal, I've got one on the left side. It is not a priority and some people never get them repaired unless they cause them too much discomfort but there is a possible danger of the intestine becoming twisted and blocked and that can be a real problem.
My doc told me that a lot of fat guys don't even know they have them so since I noticed I have two, I will take that as a compliment.
Seriously, my friend, good luck to her in her recovery and help her follow the doctors orders. Which may include hiding a Whoopie cushion on your person to get her home.
