Okay, so, I was about to go to bed, and I normally rub my eyes for a split second before attempting to sleep, but my left eye started hurting as soon as I touched it. At first, I thought it was just and eyelash, so I carefully smoothed all my eyelashes back to where they should be. It still hurt, so I blinked a bunch because I thought it could be dust. I teared up, the pain persisted. I got up, looked in a mirror, and saw nothing. I leaned back and pulled my eyelid up and then I saw a little brown splotch with a dark brown spot in the middle on the white of my eye. Now, I saw an eye doctor YESTERDAY for a yearly check up and they said nothing about a spot, although I have a freckle in my right eye, this splotch is in my left. I m very confused, and concerned. I did go tanning today and forgot my eye-covers; could it have been the UV rays? I kept my eyes closed.. But I m very concerned. Is this just a small blood vessel or is something happening?
