I would have two suggestions: a medical eye examination by a different ophthalmologist Eye MD (find one near you at www.aao.org) and second a complete medical examination by a highly qualified General Practitioner or Internal Medicine specialist.

I did a complete medical examination in recently say about 4-5 months back...that also had a routine eye pressure check...But the tests were all good and nothing came out of it. I was happy at that time but again day before yesterday I got this swelling on my right eye.
Your problem has come on AFTER your medical and eye exams so both would need to be repeated.
