hernia
Look... I'm an OR nurse, and I see hernia repairs every day. Every one is different, though there are common locations where these occur. What lays one person up for months, may only lay another out for a week.
Hernias will occur in different sizes, and require different means of repair. Some can just be pushed back in and sewn up, larger ones might require reinforcing mesh to hold things in. In any case, it is like any wound and should not be stressed until it has had a chance to heal. Squats would definitely be a post hernia repair no no in almost any instance.
