A Hello! Thank you for your photo and inquiry. Itchiness after surgery can be due to a reaction to surgical tape, bra etc. The area also looks a bit red. In my medical opinion, a topical anti-biotic ointment would better help the incisions to heal. I would make a follow up appointment with your board certified plastic surgeon to examine you in person and decide whether oral anti-biotics would be necessary as well. In regards to the flanks, I always recommend post-surgery lymphatic massages to help break down the tissue and avoid lumpiness.
