Hi, I m 39 years old, healthy no significant history. Weight 55kg, height 5 ft 2in. For past 3 months I have had heaviness towards the back and top of my left eye. My optician can see no signs of infection or deterioration in my eyesight since my last eye test a year ago. The problem started after developing mild conjunctivitis which i treated with OTC chloramphenicol drops but only for 2 days (as I left the drops at home to go on a business trip I did not complete the course) but the infection seemed to clear within 24 hours. The heaviness started within a week and has been there since, worse in morning and late at night. Many thanks for any advice
