Welcome to the forum!!!
A mini tummy tuck is much less pain than a full tummy tuck. Be thankful for that.
As far as your question, you will be swollen for a few days after the mini t/t/ surgery. This is normal. You will also be in pain for about 2 weeks. You will have swelling from 2 to 6 weeks. Your bandages will have to be changed in 2 to 5 days. Your sutures will be removed in 7 to 10 days. You can return to working at a desk job in loose comfortable clothing in about a week or week and a half.
Breast implants can be very painful post op. How are they "installing"

your implants? Over or under the muscle? Under the muscle looks more natural, but is more painful when healing.

Pain lasts one to two weeks. There will be swelling, numbness, and bruising as well. Wait 2 to 4 weeks to exercise. If you get implants below the muscle you have to wait one or two weeks to go back to work at a desk job, depending on how you feel. Over the muscle, one week should be sufficient.
I am just providing you with some basic guidelines. Let me know if you need any more info. I'd be happy to help.
Good luck to you!!!
