In this case, the patient can be treated with external immobilization with a chest belt, continuous local cold compresses, and pain-relieving medications such as Cao Wu Jia Su tablets and Paralysis Capsules. Through the above treatment, the pain symptoms will usually be relieved significantly in 2-3 weeks, and the patient’s pain will disappear completely in 3-4 weeks, while the respiratory activity can also return to normal level, and the chest belt can be completely removed. There is also no obvious pain when pressing the local area, and the swelling will also obviously subside, and the patient can be considered clinically cured at this time.
