Swollen eye lid, no eye injury, diabetic, sore to the touch, visions foggy/blurry, no insurance, no money for eye dr. help?

Possibly a stye : Try very warm compresses 2-4 times per day for 10' a time followed by gentle massages to the eye lid may help the backed-up oil gland secretions to drain. Usually this technique resolves the swelling and the stye should resolve within a week. However, if the swelling and pain increases, you should seek help from an eye md.

Potentially serious: While this could be a minor problem like pinkeye, the fact that you are diabetic, have pain and blurry vision all at the same time gives one cause for concern, i would recommend evaluation asap!
