My lower Ulna (near the wrist, the bit that bumps) hit a wall when I slipped. It's been red for hours now and painful when touched, I still have mobility in wrist and fingers. Could it be fractured?

Dr. Zakia Dimassi Pediatrics
This kind of trauma where you fall on an outstretched hand, if it is to lead to a fracture, it would be in one of the wrist bones, known as the carpal bones. In the young adult population, the most commonly affected bone is the scaphoid bone. Scaphoid fractures usually result in pain at the base of the thumb with concomitant swelling in the same area. There is also pain, swelling, and sensitivity to palpation in the anatomic snuffbox (a triangular deepening on the radial, dorsal aspect of the hand, at the level of the carpal bones) at the base of the thumb. Fractures of scaphoid can occur either with direct axial compression or with hyperextension of the wrist, such as a fall on the palm on an outstretched hand. Classically there can be pain in anatomical snuffbox. X-ray is needed to confirm the diagnosis.
