I think the key here is location, location, location. Arm or leg stitches + laughter = “Ouch, dammit that hurt!!” Abdominal or perineal stitches + laughter = “Oh damn, oh damn, oh damn, shoot me now!!”
When I had hand surgery I just put a big plastic bag over the whole affair, wrapped some elastic bands around it, and then got in the shower. It seemed to work, although I’m sure it looked stupid. Elastic pants and sports bras are the way to go - I could not do up a bra or jeans for about a month. I also couldn’t tie my shoes. So, I’m sure I looked quite fashionable in general.
Speaking of abdominal stitches, when I was a kid my teenage brother had surgery to repair a large hernia. He was finally resting somewhat comfortably in bed at home when our sweet, fat (15 pound) cat decided to jump up on the bed to keep him company. And landed right on his incision.
I swear the screaming must have been audible down the street. I’m surprised my parents weren’t reported for child abuse.
I wrapped my hand similarly a few months ago when I cut my fingertip off. I think my primary concern now is hitting my arm on the very narrow shower wall. I’ll give it a try tomorrow.
