It's been a pretty good experience. I like the results. I get worried sometimes but I guess that's normal. I did it because I wanted to even out my breasts and to get more volume.Hi I just had breast augmentation surgery about 4 weeks ago. When I'm stretching in the morning or yawning I can actually feel the muscle move the implant and I was wondering if your muscle can actually rupture the implant? I have saline implants placed above the muscle.
