Many abdominal or hip procedures can leave patients with back pain. Sometimes it is a direct operative site such as liposuction that hurts because of swelling, bruising, or both. Ice helps early on in the first few days. After that heat may be more helpful. Back pain may also result from patient positioning after liposuction of the abdomen or hips or abdominoplasty. Many patients can't stand up straight or cannot sleep in their usual positions leading to back pain. Warm compresses or baths, massage and time are the best cures. Certainly, there are rare causes of back pain not directly related to the surgery such as kidney problems that can occur during the perioperative period. If the pain persists, discuss the details with your surgeon.
