Apart from the above said symptoms, there can be additional ones like swelling, dryness in the eyes, sneezing or cough, discharge of mucus or pus and eye twitching. Some people may develop headache, neck pain and even stomach pain. If there is no additional symptom, then, you may wait for two to three days. If it does not subside, then visit a doctor. If there is any additional symptom (specially, vision problems), you must consult a doctor at the earliest.
