How Long Does Pain Last After Surgery?

Pain after surgery is expected and varies considerably by procedure. Published guidance from the Royal College of Anaesthetists indicates that acute surgical pain typically peaks in the first 24–72 hours and gradually improves over the following days to weeks. Minor procedures (arthroscopy, laparoscopy) often see significant improvement within a few days. Major surgery (joint replacement, abdominal surgery, cardiac surgery) may involve moderate pain for 2–4 weeks, with ongoing discomfort for several months.

Pain that is steadily improving (even if slowly) is generally reassuring. Published NHS guidance indicates that pain which is getting worse rather than better after the first 3–5 days, or new pain appearing in a different location (such as calf pain, chest pain, or sudden severe abdominal pain), may warrant medical review. A temporary setback or “bad day” is common in recovery, but a sustained worsening trend is different from a single difficult day.

Managing pain effectively is important for recovery. Published guidance indicates that staying ahead of pain with regular paracetamol and prescribed anti-inflammatory medication (where appropriate) helps patients mobilise earlier, which reduces complications such as blood clots and chest infections. If prescribed opioid medication, published Royal College of Anaesthetists guidance recommends tapering as soon as pain allows, as prolonged opioid use carries risks of dependence and side effects.
