Many orthopedic problems, including joint and spinal pain, are mild during the day and worsen at night. This is because most patients are engaged in various tasks during the day and do not concentrate, and at night the vagus nerve is excited and the pain is aggravated by concentration. In addition, at night, the body is in a state of rest, blood flow is slowed down, the inflammation is relatively built up, when the concentration of inflammation is higher, it will lead to increased pain. Moreover, the spine and joints remain in the same position at night while resting without movement, which also increases the concentration of local inflammation for a considerable period of time, leading to increased pain. After attention is shifted during the day, pain is tolerated better than at night. Therefore, when pain aggravation occurs at night, you should soak your feet or take a hot bath before going to bed, and do a proper bedtime massage, all of which can help to alleviate pain aggravation at night.
