Muscle strains and tears, there are mainly the following differences: first, the degree of injury. The degree of strain injury is much lighter than that of a tear, because the continuity of the muscle still exists after the strain, while the tear has an interruption of continuity, so the degree of injury, the tear is much more serious. Second, the symptoms of strains and tears are different. Strain is mainly localized pain and inflexible activities, while tears often appear severe pain, and local swelling will be obvious, the activity is basically completely limited. Third, muscle strains and tears are treated differently. Strain is mainly to let the muscle in a relaxed state, rest, about 5-7 days, with the gradual elimination of edema, pain symptoms will be significantly relieved, and can carry out appropriate activities, generally in 1-2 weeks of time basically healed. After the muscle tear occurs, surgery should be performed to anastomose the torn end, and then external fixation of the plaster should be performed, and the external fixation should be removed in about 3-4 weeks, and functional exercise of the limb should be performed, and it should take about 2-3 months to heal completely.
