For context she is 17 years old. Kinda hard to see in the pictures but for the past two days she’s been having this grayish puss build up in the inner corners of her eyes. It seems like it might be painful since she isn’t opening her eyes fully. Additionally, she has seemed to be physically a lot weaker than she used to be. Is this just normal aging and she might be getting to the end or is this some sort of disease that can be treated?
