I had the inverted t. I think it's basically the same in terms of healing and post op pain. With the inverted T, they don't remove the nipple entirely like they do with the regular double incision, so after surgery I could already feel my nipples which was a weird feeling.
I had moderate pain after surgery, but I was avoiding taking the pain pills because vicodin makes me nauseated if I take too much and I was already nauseous from the anesthesia so I didn't bother. But if i wasn't worried about nausea I would've taken the pain meds for about 4 days at least.
In terms of mobility I was moving around and making my own microwave meals by the second day and could raise my arms over my head by the first week, but it wasn't comfortable to do so until the second week. It still felt funny to raise my arms over my head for weeks, but it didn't really hurt after a few weeks, just felt like a tight sensation
