Rowan Rue,
I have had a left & right hernia done at a world renown Hospital that specializes in hernia operations, both times under local. Nice grounds & they get you up walking right away. After the op in conversation with people if something humorous is said it can be a little uncomfortable laughing or coughing. Recovery isn't overly painful, the odd quick jolt, when you feel a want to itch that is the sign of healing. I took a week off work, went for a walk each day & kept extending the distance I went. Should be loosened up mostly after a week. You are not aloud to do anything strenuous or lift anything heavy for 4 to 6 weeks.
Don't worry. Get a good nights sleep before the op & relax as much as you can. Post op, listen to your body. You will be fine. I know the waiting is a real bug.
Good luck. Be positive & take care.
Jamie
