I had breast augmentation after losing over a 100 pounds after gastric bypass. Before losing weight I was a 44DD and after surgery I range between a 36 to 38 D. Now, it's been 4 years since my augmentation and they are growing again. Is that possible? my 38D is no longer fitting...I am having to go up to a DD again... Also, when I had surgery, I had silicone implants and the lollipop cut. The left nipple has no feeling or sensation. Is there any possibility that I will get back any sensation?
