Hello, I fell, slipped on a wet step, this morning. Must have caught my leg on the edge of the step... a cut on top of a huge goose egg! I took arnica granules, 3, straight away, and put an ice pack on it and have rested for the morning. I can stand, even walk to the bathroom and back, so I don t think the kneecap us injured. But the swelling has not gone down very much, and the whole area is very sore and painful to the slightest touch. Should I see my doctor? Need an exray?
