If you go back after a week 10 days it won’t as you say tear open if you have keyhole surgery you don’t even have stitches,if you’ve had a previous hernia you may need to have an open cut repair which would take slightly longer to heal.
I’ve just had a Miniscus repair in my knee almost a month to the day I’ve been back to work for 3 weeks with no problems,you have to listen to you’re body and just take it easy with any surgery.
