Well, what kind of hernia?
I had an umbilical hernia and that was WAY rough.
One of my employee's had a "normal" hernia and he had the surgery on a thursday or friday and was back to work on a tuesday.
Me however, I was out for much longer as I had a couple other things going on (had the appendix out, ulcers and other things with my esophogus, stomach, small and large intestine).
How much pain are you in? If it is "minor" then you will be fine in a couple days. When I say minor, can you handle car rides with bumps, can you stand up straight, function normally?
Best of luck.
