Talk to Eye Specialist on Eye Allergy And Itching, Swelling

I have been suffering from this eye swelling from the last two starts with itching and then result in swollen eyes.. sometimes my eye got swelled by uper side and sometimes from the lower side.. sometimes both uper and lower sides swell. At first I didn't know what is the reason so I rub ice cubes and it happens to get after a few months it didn't turn to workout this way so I used to take T-day as an anti allergy and it works for between I'm also using homeopathic medicines but as I'm a student it takes a lot of time to be cured so I stopped using homeopathic Doctor told me at first that I'm taking a lot of salt that's why it happens and the very next time he told me that it's because some insect bite happens today after 6 months of gap and I still can't understand the reason of suggest me some good medication or doctor so that I may understand the reason and get a possible cure for it thanks!!!
