When finger swelling occurs after a finger crush injury, the hand should be immediately braked and go to a regular hospital to see a doctor for a physical examination and hand x-ray to screen for fractures.
If there is a fracture, you need to choose closed reduction external fixation or surgical incision and internal fixation treatment according to the degree of fracture.
If there is no fracture and there is soft tissue injury, rest should be taken, and local ice should be applied within 24 hours. after ice, the affected area should be wrapped with pressure in time to control the movement of the injured finger and reduce exudation. after 48 hours, local hot compresses and centripetal massage of the finger can be applied to promote recovery.
