A swollen eye may be bloated as a result of tissue leakage and bruising due to trauma. This is usually done within 48 hours of the injury by applying a cold compress, which is a cool towel to the swollen area. This will help the vasoconstriction and reduce the exudation of tissue fluid and prevent the swelling from increasing further. Alternatively, after 48 hours of trauma, you can switch from cold to hot compresses and use a warm towel at about 40°C to apply heat to the injured part. This kind of heat therapy can help blood circulation and promote the absorption of tissue fluid and bruises, which can shorten the course of the disease, so that the bruises and tissue fluid exudation can be absorbed more quickly and the swelling can disappear more quickly.
