Hi, can I answer your health question? Please type your question here...I fell off my bed onto the corner of my nightstand last nite. The corner of the nightstand impacted the rear left side of my torso just above or around where my kidney is. There was pain and then after an hour or so it subsided. Today it felt like a muscle strain or bruise. There was no blood visible in my urine. There is no redness or discoloration around the area. It feels a bit tight.
