I fell and landed on my kneecap three and a half days ago. I am able to walk with minimal pain.....as long as I don't flex the joint. The biggest concern is the intense pain if I even lightly touch the area of impact on the kneecap. Very sharp, like being stabbed by a lot of hot sharp needles. I work all day on my feet, it has been difficult but I have made it through two and a half days since the incident and three and a half since the injury. My wife is pushing me to x-ray but I tend to wait..
