A muscle strain is a tearing injury to a muscle or tendon, commonly found in the muscles of the lower back and the back of the thigh. It is usually caused by improper preparation activities for sports, too strenuous exercise, muscle fatigue or overloading. Common relief treatments include general treatment, drug treatment, surgical treatment and so on. 1. General treatment: when muscle strain occurs, within 72 hours, first of all, local cold compresses should be applied to stimulate vasoconstriction and reduce the exudation of tissue fluid, which is conducive to the relief of pain. After the pain is relieved, hot compresses can be applied during the recovery period after 72 hours, which is conducive to local blood circulation and helps the healing of the muscle injury at the same time. 2. Medication: After the muscle strain, you can use non-steroidal anti-inflammatory drugs, such as diclofenac sodium, ibuprofen and other anti-inflammatory pain under the guidance of the doctor. 3. Surgery: When a muscle strain is severe and the tendon is completely torn, surgery is needed to repair the tear. When a muscle strain occurs, you should consult a doctor in a timely manner, under the guidance of the doctor to carry out targeted treatment. Usually pay attention to do a good job of preparatory activities before exercise, appropriate rest and stretching exercise, avoid too strenuous exercise.
