Yesterday, I was at my gym class and twisted my knee oddly where there was a brief discomfort. I continued my workout that included squats. Nothing noticeable aftermy workout. A few hours later as I was sitting at a staff meeting, I noticed significant swelling and stiffnes on the outside of my knee where the IT band starts. I wasn't able to bend the knee to sit but the swelling has subsided somewhat. Still elevating, icing and taking motrin.
