my mom (age 62), who has had type II diabetes for about 3 years now, has been suffering from pain in her eye for 2 days...also has redness and swelling...but no "scratchy" feeling as if something were in her eye, no light sensitivity, just pain in her "eyeball" as she describes it...the doc does not know what it is and is treating her for conjunctivitis, which has decreased the redness, but not the pain....doc gave her lortab for the pain....what the heck could this be and could it be related to the diabetes?! thanks in advance for replies
