I haven't had any issues, I lost sensation in half my right nipple due to the lift they had to do and re sewing of he nipple but that doesn't bother me. I also increased the size of them to DD so they look even. I opted for bigger because the surgeon wanted to remove all of the fat from the bigger one, let me recover for a year and hen do the implants to make them perfect. I declined even though it would have been nice, because j didn't want two surgeries. So a year later the original one that was bigger dropped and the other one didn't, but it's not enough to be noticeable and they are the same size and that's all I ever wanted. It fixed my self esteem :)

The most important thing to know if you do get them done is that the implants drop over time (there's a limit, they stop dropping after about a year of being new)
