You seem to be complaining of pain with discharge watery. How is your vision.
It could be simple viral conjunctivitis
or conjunctivitis due to some foreign body exposure.
Mild corneal lesion or internal reaction might be present. I would suggest you to see your nearest ophthalmologist.
Till then you can use copious amount of tear substitute(Refresh liqigel four times a day) and an antibiotic drop (Moxifloxacin
e/d 6 times a day)
