 [ Symptoms ] is it possible to go undiagnosed for years  i was just recently diagnosed with genital herpes i was completely unaware that i might even possibly have them the only symptoms i had was some vaginal itching and irritation before i started my period [ Disease ] most helpful answer i always recommend that people use the antibiotic eye drop in both eyes from the beginning since it can definitely spread to the other eye an antibiotic eye drop would only be effective for pink eye caused by a bacterial pathogen many cases of pink eye are viral or even allergic so in this case the antibiotic would not likely help a viral conjunctivitis pink eye can spread even when you are on antibiotic eye drops
