Suddenly since yesterday my mother is having pain in the UPPER part of her left eye (eye lid and crease). From today there is redness in the eye, the pain is increasing when she is opening her eye, little bit tear coming out of her left eye. She does NOT have any history of migraine and sinus. There is NO itching. NO pain in retina. She has never had this type of pain before. I have attached a photo of her left eye- the area underlined is where the pain is occurring.
