Swelling of the eyes caused by a cold may be due to increased mucosal edema and secretions in the eyes, or it might be due to a secondary bacterial infection causing conditions such as eyelid inflammation or conjunctivitis. If there is eye swelling accompanied by purulent secretions, it is considered to be caused by inflammatory irritation. Topical use of rifampin eye drops or erythromycin ointment can be applied for anti-inflammatory treatment. If there is simply swelling and tearing without redness of the eyes, it may be due to increased glandular secretions caused by the cold, and medications that suppress glandular secretion along with vitamin supplements can be taken for symptomatic treatment. Drink plenty of water, rest more, and promote metabolism. (Medications should be used under the guidance of a doctor.)
