After surgery for thoracic spinal stenosis, the “old problems” (a series of symptoms caused by compression of the thoracic spinal cord) still exist and take a long time to be gradually relieved, while in many patients “new problems” appear, namely postoperative pain around the wound, especially The pain around the wound after surgery, especially when turning over or getting up, is more pronounced. What is going on here? In fact, it is very normal for patients to experience this pain in the early postoperative period. Thoracic spine surgery will inevitably cause some damage to local muscles, fascia, ligaments and other soft tissues, and it takes some time for the damaged muscles to heal. In the early postoperative period when the above soft tissues are not healed, the patient will have pain at the injury when he does the movement that requires muscle contraction such as turning over. As time passes and the tissue heals gradually, the pain level decreases geometrically and generally disappears three to four weeks after surgery. During the time that pain exists, patients can take pain medication in appropriate amounts depending on the severity of their pain. The most significant pain is felt in the vicinity of the wound 24 to 48 hours after surgery, and patients may feel more obvious pain without doing any activities. This pain will bring about a series of physiological reactions, such as fluctuations in heart rate and blood pressure, which are detrimental to postoperative recovery, and it is necessary to take analgesic measures at this time. In the early postoperative period, a variety of pain medications can be used, including analgesic pumps, intravenous infusions, intramuscular injections, external skin patches and oral administration. When the patient is basically pain-free at rest, and pain occurs only when turning, it is necessary to decide whether to use pain medication according to the pain level during turning. When the pain is relatively mild, in principle, pain medication should be stopped as soon as possible. One month after the surgery, when the patient is able to move on the floor for a longer period of time, pain is no longer the most troublesome problem for the patient, but the pain and swelling in the lower back may become the “main character” again. The soreness and swelling of the lower back may be a direct result of the surgical trauma on the one hand, and the weakness of the muscles on both sides of the spine (collectively referred to as the paravertebral muscles) on the other. In healthy adults, “disuse” muscle atrophy occurs after more than 2 weeks of continuous bed rest, and the manifestation of muscle atrophy is a very pronounced soreness and swelling of the lower back when moving on the floor, always wanting to support themselves with their arms, which can be quickly relieved by lying down. Therefore, it is recommended that patients do not “over” bed rest after surgery, in the early days after discharge from the hospital to adhere to the appropriate amount of daily activities on the ground, about four weeks after the wound pain disappeared to start doing functional exercise of the paravertebral muscles, until the muscle function to recover well, the symptoms of lumbar swelling will disappear. The specific exercise method early to “small swallow fly” and “five-point support” mainly, later can engage in swimming, jogging and other general physical exercise. The intensity of exercise must follow the principle of “gradual and progressive”, and consult a doctor if necessary. Incidentally, after surgery for thoracic spinal stenosis, in addition to pain and swelling in the lower back, symptoms such as a feeling of banding and numbness in the lower extremities, which existed before surgery, may still exist after surgery. These are the manifestations of spinal cord damage, and their recovery takes a long time, requiring patients to be patient enough and adhere to rehabilitation exercises under the guidance of a doctor.
