What's your opinion on the black scab on areola after surgery? (Photos)

Hi. Is it normal? I underwent a breast reduction with implants 25 days ago. I got this big black scabs in my left areola and I am extremely concerned about the healing and if I will need another kind of procedure to fix that. I am in contact with my surgeon, who sees me every week, but I think I could use a second opinion on that. I started using bacitracin ointment 4 days ago. Does it usually heal by itself? It doesn’t hurt, no sign of infection at all. I wonder why it happened.
