The duration of pain after hip replacement surgery needs to be judged according to the recovery of the condition, and it cannot be generalized, usually it will not hurt after 1~2 weeks. When doing hip replacement surgery, you need to cut the skin and subcutaneous tissue, and then replace the damaged joint with an artificial joint, so that the trauma caused by the surgery is relatively large, and the trauma recovery takes time; about 1~2 weeks after the operation, the tissue damage, inflammation gradually ease the recovery; however, because of the individual physical differences and different recovery conditions, the pain time has some differences. After hip replacement, you can do ankle pump exercise, muscle contraction exercise, etc. If the postoperative pain is serious, you can apply medication under the guidance of your physician.
