Last night, i noticed what appeared to be a bite of some sort near the crease of my eyelid. Place was round, red, raised, a little itchy (not today though). This morning I woke up and the redness and swelling has begun to spread towards my eyelashes, my eye is swollen, and the area really hurts. There is no changes to my vision. I am wondering if this is something just to watch or should I see a doctor since it is on my eyelid, the redness and swelling is spreading, and it is so painful (every time I blink it hurts - I think because it is in the crease of the eyelid?
