However, pain is inevitable during rehabilitation training. In fact, no matter what kind of training a patient does at home after surgery, the intensity of the training will basically lead to leg pain or wound pain. If the pain disappears after stopping training, you can resume training. The intensity of training should be the same as before, do not reduce the intensity of training because of pain. However, it is worth noting that if the pain does not disappear after stopping training, but continues, it is necessary to seek medical attention. In addition, after artificial hip replacement, many patients have similar experiences: the bones hurt when they walk a little. In fact, it is quite normal to experience this phenomenon within three months after surgery. This is because patients with artificial hip replacements do not start training their muscles until six weeks after surgery, which often results in the patient’s muscles not being as strong as they could be. A joint without muscle protection is like losing a lubricant, and two hard objects can come together, causing a sensation of collision and sometimes pain. Therefore, after the replacement of the artificial hip joint, patients often have the feeling that “the bones hurt when they walk around”. However, if the pain is not relieved after more than three months, it is necessary to go to the hospital to check the blood sedimentation and C-reactive protein to consider whether there are other problems.
