The common causes of pain below the bone are mainly the following: a. Soft tissue damage below the bone during the patient’s strenuous activity, causing significant local swelling and pain. Patients need to rest fully, local ice can be applied externally to reduce capillary exudation and avoid progressive increase in local bruising. 48 hours later, combined with manual massage, local heat, physical therapy, infrared radiation, improve local blood circulation, can promote local swelling and pain relief faster. Second, if the patient falls more serious, accompanied by local fractures, will also cause severe pain below the bone, simple external and oral analgesic drugs often can not relieve the patient’s pain symptoms. It is recommended that the patient improve the local X-ray or CT examination as soon as possible to clarify the severity of the fracture, and perform surgery for internal fixation as soon as possible to remove the local hematoma. Postoperative supportive treatment such as swelling reduction, anti-infection and analgesia can relieve the patient’s pain symptoms more quickly.
