Hello! while swimmin with my friends, I was headbutted very hard directly below the eye. It swelled up absolutely instantly and I mean before I got out of the pool I had a chicken egg sized bump instead of lower eyelid. I was advised aspirin and hot pack on it. That was yesterday. I didn't have concussion and I doubt it's broken. Today I have the biggest black eye. My eye is shut, the swelling fully surrounds it but it's mostly the bottom eyelid and it's plum purple. How long will I have it?
