I sustained a knee injury about 2 months ago where I came off a horse in armor ( I am a professional jouster) and landed on my knee. As I was wearing armor, my knee smashed hard on the inside of the armor upon contact with ground. Finished show and was in pain for a couple of weeks after. Still a tenderness at kneecap when I palpitate knee. Recently went back to work in construction (lots of climbing, squatting, end working on knees. Have just noticed significant swelling in front of knee cap. Almost like a water balloon. Is this my bodies way of protecting my kneecap while it heals, and will it go away? Never had x-rays but could possibly have fractured patella. Would I be able to walk/run painlessly if I had?
