Pain or aching in the center of the back after breast explant or lift surgery can be due to several reasons: 1. Posture Changes: After surgery, patients may unconsciously alter their posture to accommodate the healing process or due to discomfort, which can strain the muscles in the center of the back. 2. Muscle Tension: Surgery, especially involving the chest area, can lead to muscle tension and soreness in surrounding areas, including the back. 3. Compression Garments: If compression garments are worn post-surgery, they can sometimes affect posture or cause discomfort if not fitted properly. 4. Activity Levels: Changes in physical activity or restrictions following surgery can contribute to muscle stiffness or soreness in the back. Regarding wearing a sports bra post-surgery, it's typically recommended by plastic surgeons for support and to minimize movement during the initial healing period. However, the type and duration of wearing a sports bra can vary based on individual recovery progress and specific surgical instructions provided by the plastic surgeon. Always follow your plastic surgeon's recommendations regarding post-operative care, including the use of compression garments or bras, to ensure optimal healing and comfort.
