I had a breast reduction surgery and lift bilaterally a few months ago. I can't speak to having only one side done, but I can tell you that my breasts were not perfectly even before, and they are definitely even now. So it's certainly possible for the surgeon to give you a perfectly matched set. ;)
That being said, you should understand that this surgery will leave you with scars. Mine aren't bad, even just 2 months after surgery, but they are good-sized. The scar runs from armpit almost to midline (it stops short of midline, so it's not visible while I'm wearing a swimsuit, for example), then up vertically from the base of the breast to the nipple, and then all the way around the nipple (because when they lift the breast, the nipple would then be in the wrong spot, so they relocate it, and in my case, made them both smaller). If you're not going any smaller, I'm not sure if the scarring would be any different. I went from an I cup to a C cup, so obviously they had to remove a lot of skin in my case.
Anyway, after they do all of that, there's some recovery time. The first 3 days sucked, and I was on a hefty rotation of Percocet. My mom came to stay with me, and thankfully she cooked, cleaned, and drove the kids around. I was cleared to drive after 3 days, but I was really sore, and under strict orders not to raise my hands above my shoulders (washing my hair was an adventure). The bruising and swelling was pretty nasty. After about a month, I was cleared to go back to lower body exercising, and actually I was feeling pretty good by then. At 6 weeks, I could go back (slowly) to upper body exercising.
So now I'm at 9 weeks and I'm feeling fantastic! My new boobs have a really good shape, they're perky like I'm 21 again, and my back pain is gone (I know that's not why you would be doing it, but that was my main driver for having the surgery done). Anyway, I would go ahead and have the consultation. See what the surgeon says, it couldn't hurt.
For whatever it's worth, my insurance covered 80% of my surgery, and I ended up paying around $2000 out of pocket. I would imagine that if insurance isn't covering any of it, it would be a lot more expensive (because there's no negotiated rate/ no insurance company forcing the doctor and surgery center to write off a portion of the cost). Anyway, I hope that helps!
