The best results happen with peri if you are smaller chested, so your results will very if you are a B or larger. I had one doc who would do a peri on me the other wouldn't. In the end I chose the doc that wouldn't because I knew my results would not be good on a peri. While I have scars in the end I will not need revisions, another thing I have heard of if you are larger and do peri. If you are smaller and can definitely go for it. As you can see with Alex the result are great.
As far as healing I had surgery in August and not much pain , but was on medication for most of the time. Lifting has been another story, I started to workout to soon and that caused swelling and lift at work so it will be a while until the final swelling (from lifting too early) goes down.
