2 wks after Breast Augmentation, when I lift my arm, I have 4 raised lines pulling at the bottom of my breast it hurts. (photo)

2 weeks is early and your breast is swollen which adds tension on your skin. Additionally, if you pull your arm up like your doing in the picture, a person who did not just have a breast aug will feel the tissues pull. Give yourself time to heal and don't pull your arm up like that. I don't see any reason why you would have to do that this early in your recovery. Call your surgeon and see them in person for their care. Your result looks nice by the way.good luck

You have Mondor’s superficial
thrombophlebitis. This is an inflammatory process that involves superficial
veins of the breast and chest wall. A tender band or cord is often present and
represents the inflamed superficial vein. Mondor’s disease is benign and
self-limiting, meaning that it will resolve without treatment. Treatment of
Mondor’s thrombophlebitis involves warm compresses, non-steroidal
anti-inflammatory drugs, and massage. Mondor’s cords may take up to three
months to resolve. Discuss this with your surgeon for additional
recommendations. Best wishes.

The bands will go away. It is called Mondors and happens rarely after breast implants. You can take medicine for the soreness. It can help to massage the area. Rest assured it will get better.
