I don't know about your chances for a successful looking surgery after a reduction, but I can tell you this much. I had a reduction. Down to a low C, high B. I wanted to go smaller, but my plastic surgeon was kind of a moron apparently. Still I'm grateful that it doesn't take as much effort to bind anymore.
My skin is very pale and the scars have faded for the most part. Honestly it looks like a bad photoshop job. lol. The two big lines where normal chest surgery scars would be are there, but the ones running upward, and around the nipples are pretty much invisible now unless you know what you're looking for.
It's been several years now, and they're still more tender than they were before the reduction. Though it is easier to bind now, I also have to be very careful. If I bind very tightly at all it hurts, a lot, and will continue to ache for a few days afterward.
At least the back pain is gone for the most part. I would suggest being very clear with whoever does your surgery that you want to go as small as possible. Make sure he gets it. I was pretty clear, and I still ended up bigger than I wanted. Though after the surgery I was still relieved to get rid of a good portion of chesticle.
I say, go get a referral to a plastics guy, have them look you over, take pics for insurance purposes if you're after that sort of thing, and see what he says. Doesn't hurt to get a consultation I spose.
