There are two important symptoms that I want you to pay attention to:
1) the rash is ONLY affecting ONE eye. This is weird. Usually allergies affect both eyes.
2) It's WRINKLY. The wrinkledness is NOT from scratching or contact; I've been careful not to touch or rub my eyelids.
3) The small region of flaky, wrinkly skin, the size of a pea, appeared under my brow maybe more than a week ago and stayed that way for several days until spreading.
4) The corner of my eye would be itchy, and other small points around my eyelids would be itchy, BEFORE the rash "appeared" at those particular locations. In other words, you would see the rash under the brow, but the itchiness would somewhere else - at the corner of my eye.
