Well this was 5 days ago, I was sitting in my balcony and a small insect came near my eye , I shooed it away and after 1-2 hrs the corner of my eye near the nose started to itch and scratch and sometimes burns. Well i thought it will go. Then next day i just touched near the eye corner and i felt pain in the upper eyelid corner inside the skin. Next day again i touched it can the pain was not there but a small round bumb was there instead of the pain at the exact same place. Well it doesn't have pain , but it itches, scratches and burns sometimes. Well i have brought eye drops to cool it. Well its been 3 days that small round thing is there inside, what can it be and what can i do to cure it.
