Clinically, according to the severity of the bruise, different treatment methods can be taken: a. If the hand is struck by external force, and the bruise caused by local soft tissue capillary rupture, this can be done by local ice to reduce tissue exudation. 24 hours later, capillary bleeding stops, hot towels can be used to wet compress. Oral bruising pills, swelling pain and other drugs can promote faster absorption of bruising on the back of the hand; second, if the back of the hand is severely damaged by trauma and impact, accompanied by the formation of local fractures. At this time, the bruising is more extensive, and the effect of using drugs for analgesia alone is not good. Patients need to improve the local X-ray examination to clarify the severity of the fracture. Surgery can be performed as soon as possible to remove the hematoma to promote the absorption of bruises and improve the pain symptoms.
