Problems with csection?

Hallie • Had an ectopic in November 2015. Baby boy born March 14 2017 & Baby girl born March 19 2020.
It's been 7 weeks since I've had my csection. My doctor told me he's going to have to reopen the wound and cut out the dark edges. Has anyone been through something like this? I've had a nurse coming to my home a few times a week to pack and clean it but I guess it's not helping. If anyone has been through something like this, how long did it take you to recover?
