My right eyelid started bothering me 3 days ago. Yesterday, when I woke up, I noticed it was a little swollen. As the day went by, it started hurting when I blinked and today it is a little more swollen than yesterday, but not too swollen. It hurts when I blink and the top corner of my eye is tender to touch. There seems to be no signs of anything resembling a stye. I applied some ice last night to see if the swelling would go down, but it doesn't seem like it will. Other than the swelling, my eye is not red and there is no discomfort besides when I blink.
Could this be an injury? my dog kind of bumped my eye when I was playing with him, but nothing major. Will this go away by itself? or could it be an infection? there is no redness, itching and the eyelid just looks swollen, but not red nor bruised.
