its EXCEMA!!!! get your DR. to prescribe you Eledel and use it at your first sign of symptoms and you can keep it under control, and never have problems again. Of course it will come back (most likey when you have bad allergies) but if you just put a little Eledel on it you wont end up having trouble :)
us organic stuff too, it could be the chemicals
a pharmacist told me she had the same problem and that it was a fungus, (dirty eye makeup) use Lamasil (athletes foot creme) and a little moisturizer because it will dry the eye out worse but it does seem to be working so far(past couple of days)
Red, painful and severe swelling are all symptoms that call for an in person exam by an Eye MD. Find one at www.aao.org
