If swelling of the eyelid occurs after eye trauma, the swelling will gradually go down after 3-5 days. After eye trauma, the eyelid skin and soft tissues are rich in blood flow and are prone to swelling and pain. It may also be accompanied by skin bruising, which may affect vision in severe cases. In the early stages of eyelid swelling after trauma, ice packs can be applied cold to reduce inflammatory exudation and prevent swelling from increasing. After 24 hours, you can apply warm compresses and take oral medications to promote blood circulation and resolve blood stasis. If the pain is obvious, you can take oral non-steroidal anti-inflammatory and analgesic drugs to relieve the symptoms of pain. If there is eye congestion or eye visual impairment, further examination should be conducted at the hospital, and if there is eye damage, further treatment is required to avoid serious complications.
