Eye Infection. Doctor should i consult?

Irritation, itching, swelling, redness in eyes. Since the last 10 days! I consulted a physician 7-8 days back, earlier he said that it was in allergy on face and in the next sitting he said its become an infection due to the allergy, probably conjectivitis. So he prescribed some meds, which I have been using since past 4-5 days but the situation still persists, at times there is this uncontrollable, irresistible urge to rub my eyes and I have rubbed my eyes on previous ocassions and my eyes get big and swollen in less than an hour getting reddish and with it comes pain and its very difficult to open my eyes after that for some time. Sometimes it gets okay, eg, twice for 2 days it looked like its getting better but then it got back to the same state again, and it doesnt seem to be improving, also there's swelling on my face too, the cheeks seem swollen up.I don't think going back to the same doctor is a good idea as I've already done that twice. Which doctor should I consult?
