The Breast Reduction surgery itself will not be painful, as you will have anesthesia given before the procedure. During your recovery period, you can expect to be given instructions for pain medication that you can use to diminish discomfort. Injection of a long acting pain medication significantly diminishes pain to a level of minimal discomfort.
It is normal to experience swelling, soreness, and bruising. Your breasts will probably feel tender for a while. By following the post-procedure instructions laid out by Dr. Nikfarjam, you will be able to manage any pain you experience after the surgery.
