hi there, you seem to be suffering from conjuctivitis. There are various causes for the same which include viral, bacterial, fungal, allergic,or due to foreign body. Your symptoms are more suggestive of a viral origin and the inflammation at the corner of the outer eye is due to maceration due to tear/constant rubbing. You can use eye drops that contain an antihistaminic along with an antibiotic to take care of the reddness and to prevent getting a superimposed bacterial infection
. Viral infectioons are usually self limiting. If it doesn't get better with the eye drops then you may visit an opthalmologist to rule out any injury
to the cornea
due to foreign body. Do not rub your eyes with a rough tissue or cloth and do use warm water to wash your eyes frequently to get rid of the scab or secretions periodically. Hope you recover soon,.take care.
