Re: Sports Injury - Knee
Knee cap impact, eh?
It's possible you aggravated the bursa, that's a little sac of fluid on top of the kneecap. Or you might have a bruise in the bone, or you might have damaged the cartilage behind the kneecap.
Regardless of what anyone tells you, don't run on this until the pain is gone. When I bashed my kneecap, I remember it took a couple weeks to settle down, and a couple months to fully heal.
Icing is just so important, especially if it's the bursa. Get the swelling down, and you control the pain. Check out that cream the physio recommended. If it's an anti-inflammatory, it might be really helpful.
Give it time. Avoid kneeling, running, or anything that hurts but go ahead with gentle activities that don't hurt. Bend your knee through a full range of motion if possible, to push the swelling out.
