How would you recognise conjunctivitis before a treatment?

Conjunctivitis, or pink eye, can be recognized by symptoms such as redness in the eye, increased tearing, and discharge that may crust over the eyelids, especially upon waking. Patients may also experience itching, burning, or a gritty sensation in the eye. Additionally, conjunctivitis can be either viral, bacterial, or allergic, which may influence the type of discharge and accompanying symptoms like sneezing or a runny nose in allergic cases. Consulting a healthcare professional is essential for a proper diagnosis before treatment.
