I have small reddish bumps between my eyes and bridge of my nose, (closer to my eyes). They don't hurt unless I rub my eye, even then it's not really a pain it's more of an irritation. I've had them before but shrugged it off, they go away after about a week, but come back, randomly. I thought it was my make up, however I have since quit using make up after the second time they appeared. They don't really look like blisters or warts or anything like that. They look more like irritation and swelling due to a clogged tear duct, and I don't think they are styles, as I have had those, however I have no idea that's why I am here. They don't have any fluid in them that I can see or am aware of. What are the most common possibilities of what it could be, what causes it to happen,and how to treat/prevent it?
