Sounds just like pink eye to me! And you'll need and antibiotic for it maybe you can go ask a pharmisist if there is any over the counter thing that might help it!!

in the corner of my left eye lid when i pull back on it ,it releases a white pus and it smells also through out hte day it leak this same pus which is very nasty can please tell me the cause of this

The condition of a white puss being excreted by the eye and drying up inside the eye whilst it is closed causing the eye to 'dry shut', is actually as the result of a blocked tear duct. There a several causes for blocked tear ducts including severe sinus and also conjunctivitis. A lot of people confuse this condition with conjunctivitis when in actual fact conjunctivitis is just a reddening of the conjunctivi (outer most area of eye due to a viral infection). Hope this response helps. Cheers.
