My left eye has been very irritated , itchy , watery , with a very burning sensation , sometimes reddish for about 3 weeks .. my lacrimal caruncle is swollen and red compared to my other eye ...
I've been blinking a lot because if it stays open it will get very watery and start getting too blurry .
I have been using itchy eye eye drops but don't seem to help at all ..

What could it be ... Should I look for immediate help ?
