I am a 19 year old female. for the for two days now i have started to notice that my left eye is very tender when i touch it. i woke up today however and it hurts to just blink my eye. When i looked in the mirror i noticed that the inside corner of my eyelid is a reddish purple color. there are no bumps of any kind around that area and i have not gotten hit in the eye. what do you think is wrong with my eye
