It seems from the history that you are having symptoms suggestive of acute conjunctivitis with involvement of the cornea
called as keratoconjunctivitis
. Most of them are caused by viruses like adenovirus and are very contagious.
The treatment is mainly by antibiotics to prevent secondary bacterial infections and antiinflammatory drugs for treatment of inflammation.
Since you are having symptoms suggestive of corneal involvement like sensitvity to light I advice you to consult your eye doctor at the earliest for treatment to prevent further complications.
