This is concerning my 27 year old son, who has Down Syndrome. He is non-verbal so he can not answer questions, so I have to play detective. He saw an urgent care doctor 4 days ago. His face was very red, it looked like wind burn and his eyes were red, but not putting out any sort of discharge. They gave him eye drops and Cephalexon 500 mg three times a day. His symptoms have not improved, his eyes are very sensitive bright light. Should a wait longer for improvement or get him to an eye specialist?
