Scab fell off from my stitch 3 weeks after breast augmentation (Photo)

Don't worry. Scabs falling off are all part of the healing process. As long as you don't see or feel any other change in your breast, you are fine. Keep the faith. Your breasts are going to look great!

Thanks for your photo and questions.  It is difficult to tell from your picture, but it is unlikely that you will have any significant issues from the scab falling off.  It is part of the normal healing process.  Make sure you speak with your plastic surgeon if your are concerned.
