Symptoms of soft tissue injury include pain, swelling, activity limitation, localized breakage and so on. 1. Pain: initially caused by trauma hematoma compression or inflammatory reaction, and later mostly caused by the accumulation of local metabolites and stimulation of local nerves. 2.. Restricted movement: active movement is limited, passive movement is still possible. If the treatment is not timely, the inflammation leads to tissue adhesion and atrophy, which can limit both active and passive movement. 3. Local breakage: local skin or mucous membrane is broken, and there is a fissure to communicate with the outside world, which is manifested as limited pain, and there is abrasion on the skin surface of the wound of abrasion, accompanied by exudation of tissue fluid and punctate hemorrhage; the wound edges of contusion wound are not neat, and the surrounding tissues are more heavily contused. When soft tissue pain and swelling occur, it is recommended to go to the hospital in time for targeted treatment or therapy.
