So the fact that it has worsened over the past 2 days shouldn't be of any real concern? Also, is it really possible to have a superimposed bacterial infection when I've been on anti-biotic eyedrops since Monday? How long would you generally expect this condition to last and what is my level of contagiousness at this point? I am a student physical therapist on a clinical internship working with kids. I only have room to miss this week. I have to go back Monday.
