I would confer with your surgeon. Our protocol is to shower 24-48 hours after surgery. I personally cannot stand to go without a shower for longer than that so I understand patients' impatience. Its 24 hrs if we do not use a rubberband/penrose drain for my patients.
Thank you for your question. I would discuss this with your surgeon. Everyone has a different approach to gynecomastia surgery.Best WishesTheodore T. Nyame MD
