17 days since implant exchange surgery (400 cc silicone), and nipple reconstruction. Am active but not exercising. Occasionally lift and carry heavy things. Trying to limit it. Can I do damage carrying groceries or briefly lifting something heavy? If so, what kind of damage and how would I be aware of it? Still have some pain beneath my breasts (especially after exertion) and aches now and then. Is this normal at this stage?
