how long has this been going on ? How is the vision ? are you sensitive to lights?
from the symptoms you describe, and the lack of response to the strongest antibiotic we have, it is apparent that you have something more serious than a conjunctivitis (pink eye). More likely, you have an inflammatory condition called iritis or scleritis, both of which are autoimmune inflammatory conditions of the eye and need to be carefully diagnoses and treated by an ophthalmologist. You need to get in tomorrow with an ophthalmologist for proper diagnosis and treatment which usually includes careful use of topical steroids (steroid eye drops). With treatment, this gets better in a matter of a day or two with complete resolution most often in a week or two, I hope this helps, I wish you well, Dr. Stevens
