I woke up last night feeling like there was something stuck in my eye, and it was painful enough to wake me up suddenly. I went into the bathroom and rinsed my eye out with water, and the only thing that helped it was dripping water into my eye. I noticed there was a long blister looking thing on the inside of my eye, between the eyeball and lower lid crease. My eye is still puffy today, the thing is still there, but my eye isn't oozing and it isn't very red.
What is it!?
