I was jogging for the bus. I wasn't in a full sprint or anything like that.
In mid run, I heard a "crack" and felt a pop, and a sudden rush of pain.
I was in a lot of pain when lifting my leg in a bending motion, to climb or go down stairs. There was some swelling in the back of the knee, and a bit of instability.
This morning the swelling is gone, pain is greatly reduced. But still having difficulty/instability going up and down the stairs. Walking with a bit of a limp, because I'm not putting full weight on the knee (left knee).
So, LGP "doctors", does it sound like an ACL? If the knee improves over the next few days, I'll let it go. But if it doesn't, I'll go to a doctor. But I want to at least have a general idea of what it might be going in.
