The swelling of the boxing hand is due to damage to the soft tissues of the hand during boxing, resulting in poor blood circulation. First, you must stop boxing, apply a cold compress locally, elevate the affected limb, and if there is no relief, choose a hot compress for the hand after 24 hours to promote blood circulation, and apply a local ointment that activates blood circulation and relieves swelling and pain. Secondly, if there is no relief within a short period of time and the swelling and pain are progressively aggravated, it is necessary to go to a regular hospital in time to improve the X-ray of the hand to see if there is a combined fracture. If there is a combined fracture of the finger bone, external fixation of the hand in a cast or brace may be required as an adjunctive treatment. During the treatment period, eat a light diet, eat foods with high protein content, do not eat spicy and irritating foods, and review regularly so that complications from swollen hands after boxing can be effectively controlled.
