Help! Swollen Eyelids (Both side) Help!

Dear Doctor, My eyelids are so swelled from last 15-20 days, specially when I wake up and they're all puffy. And after 8-9 hours swelling gets little less visible as compared to in the morning, but doesn't get better completely. Every now and then, they're so swollen that it looks like a ping-pong ball has been cut in half and inserted under my eyelid. I can't figure out what makes this happen. I haven't changed anything (make-up, pillow, detergent, etc.) In fact I'm not wearing any make up at all from last 2-3 months. I went to meet doctor as well, he suggested me to get my thyroid and kidney tests done. Reports are normal. Also my eye sight is absolutely fine. He said he's not sure what the problem is. He game me these 3 medicine, said it could be allergy. Flarex Alcon, Chlorosun-H eye ointment, and Levosyd tablets. I have completed the course but I don't see even 1% improvement. Please help!
