In clinical practice, it is a common clinical manifestation for patients to experience soreness, numbness, swelling, pain and itchiness. For example, patients may experience soreness when excessive lactic acid accumulates in the muscles after exercise and is not metabolized in time. If the patient is injured by external force, the patient will have local numbness and other manifestations, accompanied by local muscle strength reduction. When the patient suffers from external force, the patient will experience distension due to poor local qi and blood flow, stagnation of qi and blood stasis, and obstruction of meridians. The patient will also feel significant pain in the injured area if a large amount of inflammatory factors are produced in the muscles after the external force, and the inflammatory factors will stimulate the surrounding nerves. If the patient’s skin or other parts of the body have an adverse reaction to the external force, the patient will experience itching. Therefore, the patient should consult a doctor promptly after the appearance of soreness, numbness, swelling, pain and itching, and receive a good treatment after the doctor gives a clear diagnosis and takes the correct treatment.
