What Causes Mild Pain And Discomfort In The Creases Of Right Eye?

Hi, I m a 36 year old male in good health. About a week ago, I started having some minor discomfort in the crease of my right eye, lower lid. I didn t think anything of it, but it is increasingly becoming more of a problem. It feels like almost a pimple under the skin, but it is relatively small in nature. My wife doesn t see any swelling, although I feel like there is some. It causes me slight pain when I rub it, and my wife says she sees to small brown dots on my lower eye lid. Any ideas on what s happening? I m a truck driver, so my sight is huge, but I am also constantly on the move, so getting to a doctors office is difficult. Thanks!
