R.; not for the faint hearted, styes are not from pregnancy, i saw a program once of what they were, actually styes are from the little microscopic cute little guys that live and clean your eyelashes, they are hard at work, a sty happens when one cute little guy goes in your eyelash hole that holds the hair in, and he goes about his daily chores, cleaning , getting the hair clean as he is supposed to, well there is more than one that works there, sometimes you get an overactive worker and he like to think its not been cleaned, so he too comes into the same hole with a fellow worker, little does the first worker realize he has been blocked in and canot get out, well its such a deep chasm for these little guys, someomne blocks the entrance and he is stuck there, there he takes a little nap, well this nap is sooo long that our bodies need to get rid of napping workers, and it puts a protective blanket over him, which is your bodies way of getting rid of sty guys, ahahahah that nap, therefore we feel the effects of a sty, but dont fret the other little guy will come and clean and make sure its clean for yah later, this was a true story i dressed it up a bit, so you can handle the truth, they say guys get stys more often casue we women are clenaing our eyes more often than a guy does, i would not think it has anything to do with pregnancy, however it could be some homrmone that makes them produce i dont knwo, you cant see them nor can you try, unless you have a very very very powerful microscope, so dont fret over them, its how we are made, we have them cleaning all over our bodies with out them we would die, so take to heart, and wash your face more often, our bodies can succreet more oils at this time so maybe the over time horn went off aand they sent out more workers, i dont know, ahhah just enjoy the little story and dont worry about them, if they are bothersome i would suggest a dr, not sure if he can do anything, or if they got anything to send some workers home, ahahah have a good day D. s
