On my right hand, on the pinky side, is that the ulnar bone or the radius bone? At the wrist point, where I been my hand or wrist, I can tell that that bone is larger than the one on my left wrist. Why would the right be larger and not the same size as the left? I did injure my wrist a few years ago, it was a sprain and a ruptured ganglion cyst in my hand. I fell on it while my hand was outstretched. I m not sure if this is a swollen bone or something or from that injury or what? But my doctor once said she thought the other one was larger as just the same as the other. What are some ideas as to why it is larger than the left wrist bone? Thanks
