Hello Adenovirus is major culprit in common viral conjunctivitis Having said that treating ophthalmologist is best person to answer this

It May not be heroes. Pl consult.

See the herpetic ulcer is extensive painful, watering and extensive redness as you already had physical consultation, every ophthalmologist checked cornea with stain, so only after the checkup he had excluded the herpetic ulcer, as you got completely recovered, its very less chances that you are having any herpetic ulcer. Soo it might be simple conjunctivitis only
