At 24 hours after breast augmentation, many patients describe tight pressure, soreness, and muscle spasm rather than sharp pain. The intensity varies widely, but it should usually be manageable with the medications and instructions your surgeon provides. Pain is not determined only by the cc number; placement under the muscle, pocket dissection, skin tightness, implant size relative to your frame, and your own pain tolerance all matter. The first 2 to 3 days are often the most uncomfortable, then symptoms should gradually improve. Contact your surgeon promptly if pain is severe, suddenly worsening, mainly one-sided, associated with rapidly increasing swelling or marked asymmetry, fever, spreading redness, drainage, chest pain, or shortness of breath. Otherwise, follow your surgeon's medication, bra, and activity instructions closely during the first week.
