So A Couple Of Weeks A Go I Had An

So a couple of weeks a go I had an allergic reaction in my eye which showed similar symptoms of Pink eye. I bought some pink eye drops and tried my best to stay out of my eye and wear glasses to protected and in time the redness went away; but the over night crusting still occurred. so I continued to use the drop and clean my eye out at least two to three times a day and the crusting started to slowly go away. Once the crusting started to stop it left a dark ring around my eye and now it is now having a puss bump on my eye lid and on my bottom eye it gets very dry and cracks. So now the puss bump is causing my eye to crust again and I once again try to keep it clean but this time I am not using the eye drops. I believe I should most likely do see a doctor, but is there anything I'm doing wrong or missing?
