Eye pain with headache for two days and a slight cold, especially worse on eye movement, is often due to sinus pressure or a viral infection affecting the eye muscles. Rest your eyes, reduce screen time, do steam inhalation, stay hydrated, and use a warm compress to ease discomfort. Get good sleep, avoid bright light, and notice any redness or changes in vision. If pain persists, worsens, or affects vision, consult a doctor to check the cause and guide proper treatment.
