36B to 36DD, 5 days post op. Right breast has a ridge derail more noticeable when I flex. Is this normal at this point? (Photo)

Congratulations on your breast augmentation.  The depression that you see is likely the edge of the pectoralis muscle when you contract your chest.  I would recommend that she would not contract the muscle but allow yourself to heal and recover before doing so.  Of course see your plastic surgeon for advice.

Hello,Thank you for your question and photo. Your fold appears irregular at this point. It is difficult to say if that is because you are flexing. I ask my patients to avoid flexing or upper body  weight bearing for a minimum 6 weeks. I also provide a supportive, compression bra to be worn at all times for 8 weeks- further supporting the position and shape of the implant pocket. I recommend that you follow up with your plastic surgeon about concerns and ensure that you follow their post op instructions carefully.All the best

Be careful flexing at this point. You do not want to pull something and get a post op hematoma. Let everything settle for a good month before worrying about this.
