Slipped & fell Sat night. Swelling on wrist gone but still dull ache & pain at times. Can now move all fingers. Certain movements are very painful but better than it was. Do I need X-rays? Must I see doc first. Or can I just get a wrist guard?

You may have. just sprained the wrist with your fall or fractured some bones. An X-ray will help differentiate but that requires a prescription from a health care professional. You want to be evaluated regardless to avoid long term problems with the wrist if it is not treated appropriately now. Bite the bullet! Go see an orthopedist now. It will be to your long term benefit.
