The swelling you describe on the white part of your eye called the sclera appears to be what is known as Episcleritis
. As the name suggests, this is an inflammation of the sclera commonly seen in patients, often women with a history of rheumatic or rheumatoid arthritis
. This is common but not mandatory. If this is the first time you have the problem, a blood work up is not mandatory. Treatment involves eye drops containing an antiinflammatory component like Ketorolac
used 3 times a day and a low potency steroid
eye drop that does not elevate eye pressure like Loteprednol used 4 times a day for 5 to 7 days, not more. This condition is not related to the stye
and is just an incidental finding. The stye may be treated with a local application of antibiotic eye ointment.
