Ulnar nerve entrapment occurs when the ulnar nerve in the arm becomes compressed or irritated. It can cause numbness or pain in which areas?

• A. Thumb and index finger
• B. Shoulder blade region
• C. Elbow, hand, wrist, or fingers
• D. Toes

Answer: (C)

Nerve entrapment shows up in the area that nerve supplies. The ulnar nerve runs along the inner forearm and into the hand, providing sensation to the little finger and the inner side of the ring finger, and it also controls several small muscles of the hand. If this nerve is compressed, you typically feel numbness or pain anywhere along its pathway—from the elbow through the wrist and into the hand and fingers. That pattern matches symptoms in the elbow, hand, wrist, or fingers. The other regions listed don’t align with the ulnar nerve’s distribution: the thumb and index finger are mainly served by the median nerve, the shoulder blade region isn’t a typical ulnar sensory area, and toes belong to the lower limb nerves.
