Hi Doc, I am a 29 years old female, residing in Noida, U.P., India. I have a bad itching in my both eyes since yesterday. In daytime I restrain myself from rubbing my eyes but during night I rub them unconsciously. Because of which, both my eyes are swollen. I am using 2 Eye drops -- IF2 and Tears naturale thrice daily but no relief yet. Please suggest what to do? I am highly allergic to sulfa.Thanks
