I had pink eye and finished my prescription eye drops about a week ago, but my eyes are still red. no pain, kind of itchy, and some crust/eye boogers. do i still have pink eye?

Yes...: Pinkeye is a non-specific label that can apply to things like airborne allergens that trigger allergic pinkeye, irritants, viruses& bacteria. You may have been treating bacterial pinkeye when it was something else. You may have had an irritant reaction to the eye drops. I doubt you are contagious, but if the eyes are pink you have pinkeye. Another eval may be needed.
