What Should I Do About Bacterial Pink Eye With Pus, Itchy, Watery Eyes, And Bloodshot Redness For Three Weeks?

I am having a problem with pink eye in both eyes. I am sure that It is bacterial. I have puss and itchy watery eyes and my lids stick together in the morning. My eyes are terribly blood shot. I have had these symptoms for three weeks. I have tried allergy drops, Silmilasan, and Lumify for redness. The Lumify helps with the redness but not entirely. I do not have any known allergies. I have had a stye in my left eye, but it has cleared up on it s own.
