What is This Line Beneath my Breast Augmentation Incision?

Thank you for the question.  Your photographs demonstrate Mondor's veins ( inflamed veins). Your plastic surgeon will always be your best resource when it comes to making accurate diagnosis and treatment recommendations.   The use of anti-inflammatories and warm compresses may be helpful to expedite resolution (check with your plastic surgeon).  Resolution of this inflammatory process may take several weeks/months.Best wishes.

An anchoring stitch from the breast to the chest wall

When I use an inframammary incision, I place firm anchoring sutures to "set" the bottom of the implant pocket. These sutures can cause a pull in the early post-op period that can cause a vertical line under the breast when raising the arm that looks similar to the picture you've shown. Massage will help loosen these tissues and the strong sutures I use weaken and dissolve over time as the body heals and forms a pocket around the implant.

Clotted Superficial Vein (medically referred to as a Mondor's Cord)

A Mondor's Cord is a clotted superficial vein after breast augmentation that classically presents with mild pain and a slight blue tinge and a vertical ridge when raising the arm like in the picture you submitted. Treatment is non-surgical with warm compresses and massage and should resolve without problems.

Hope this helps,
