Whats wrong with my Boyfriends knee!?

Question

My boyfriend was golfing 1 day and he went looking for a lost ball and it was in some shrubs and bushes and he feel down by tripping over a root and he thought he felt his knee pop out of place and pop back in so now its swollen the day after and he can bend it and put weight on the knee and walk its just swollen and he says when he tries to bend it.It hurts.

Answer 1

To reduce the swelling take some Advil, and maybe put an Icy-Hot pad on it. If the pain persists. I would just go to a doctor to see if he needs a brace for a few days or something. Hope this helps.

Answer 2

He may have torn a ligament.  I'd get medical advice from a board certified doctor, not a board.
