hello, My son is two years old, his ledt eye starting get since Christmas, we went to Urgent care and his regular doctor several times and they have said infection and gave him antibiotic drops and it came back again and the doctors said it s eye infection. It s not getting better, still red, very little discharge on the eye, and the during the past month, he had a red sty on his eye twice. The eye specialist couldn t examine him since he was crying so much, but said most likely it s allergies and the sty will go away on it it s own, which did. But the redness is not going away and the eye looks smaller than the other one. Can you please advise what may be causing this? Thank you
