Can a small internal dent/lump near incision be normal? Can it be due to internal stitches? I only feel it when I was underneath

It is best to be seen by the plastic surgeon so they can determine what the nature of the problem is.

Due to irregularities and swelling there can be contour issues in the incision after breast augmentation. I don't think you have anything to worry about but it's good to check with your surgeon.

Thanks for the question. In my practice, after performing a breast augmentation I recommend to my patients to limit the movement of the arms for two weeks. After that, you can move your arms taking care and always with common sense. In this regard, it's not advisable to carry heavy weights to prevent the implant out of position, and allow the formation of the physiological capsule around the implant, also to avoid pain and breast swelling.

Thanks for your inquiry.  Yes, you can feel the deep stitches sometimes.  If there is no redness or signs of infection, then you are probably right.  Please cal your surgeon to discuss if you are concerned. 

You are correct.  What your feeling on your incision line is most likely sutures.Best Wishes,Nana Mizuguchi
