Horizontal line between bottom of nipple and breast crease 4 days post Breast Augmentation?

Thank you very much for your question and photographs.
At four days’ post-op, it is too early to diagnosis a ‘double bubble’.  From your pictures, it would seem as though
the line from your old breast fold might be apparent, which may dissipate over
time. This may take three to six months, however, as the breasts heal and
swelling resolves. I would recommend that you speak with your operating surgeon
for his/her advice and carefully following their recommendations.

Thank you for your question. An in person evaluation is required to answer your question. It is in your best interest to be seen by your nurse or surgeon to have your questions answered. Best, 

Dear Jessica,   Thanks for submitting your pictures. It would have been helpful to see your before and after pictures in full size. Being as it may, I see the mild indent that worries you, however,  it is very early in the healing process and it might be just due to swelling , which will subside in 2-3 weeks.   As far as implants displacement massage, it is a great idea. All my patients start it on the 3rd day after surgery, which is when the capsule (scar around implant) starts forming and it is soft enough to be stretched by the massage, creating soft and natural looking breasts.                   Best of luck,                                     Dr Widder
