Symptoms of muscle tear mainly include pain, swelling and activity limitation. 1. Pain: usually mild with localized pressure pain, and severe with tear-like severe pain, accompanied by muscle soreness, the pain is aggravated by the patient’s activities. 2. Swelling: Most patients also have localized swelling. If the swelling is severe, there will be obvious blood stasis under the skin, and in severe cases, hematoma will even be formed, which is usually caused by muscle bleeding. 3. Restricted movement: Torn muscle can lead to restricted movement. If the muscle is completely severed, when touching the area, there will be depression or abnormal bulging at one end, accompanied by local spasm and dysfunction. Muscle tears are caused by excessive contraction or elongation of the muscle beyond the tolerance of the muscle tissue, so it is recommended to do warm-up exercises before exercise and exercise moderately. When patients experience the above symptoms, they should seek medical treatment in a timely manner and under the guidance of the doctor for regular treatment.
