My 21 year old son thought he had pink eye and went to urgent care and was given antibiotic drops and was told he had a sinus infection. Those drops did not help at all. He has a friend whose dad is an optometrist who gave him some steroid drops and his eye got better. The drops are gone and his eye is almost swollen shut and is extremely light sensitive. It does not itch but is uncomfortable, swollen, red and crusty Have any ideas?
