I'm not quite sure what it could be but I'm almost 100% sure I have a stye. It's right on my top eyelid and hurts so bad. I read that you should apply a warm face clothe which I have and also green tea packets help but I'm out so I have to get more. I haven't  had a stye since I was a kid.. Anyone have any helpful tips to get rid of it?
