Discomfort in eye. Am really fed up.

I had an eye infection in the month of June-July and got cured in the first week of August. But even after that I felt discomfort in my right eyes. So I consulted with my doctor and he told me that no need to worry it would be fine in few days until you use Refresh tears. Now it's November & I don't feel any improvement in my condition. Specially in the morning when I wake up I feel heaviness in my right eyelid. Sometimes I feel burning sensation, itchiness, moderate pain, swelling in right side lower eyelid and stickiness... Regarding all that issue I consulted with my doctor again but he didn't find anything. When I was infected he prescribed me F M L - T (for 10 days) Gatiquin -p ( for almost 30 days) Refresh tears (using it till now) I am really fed up... 😞😞😟
