The “funny bone” as it is famously known, is actually a nerve – the ulnar nerve. It continues from the neck region right down to the hand, providing sensation to the little and ring fingers of your hands. Small muscles in your hand are linked to it, and these are very important for what we call a “power grip”. Through an opening at your elbow, the ulnar nerve passes – this opening is called the cubital tunnel. When the ulnar nerve gets compressed gradually or has been in a state of too much pressure bearing down on it, the condition is known as cubital tunnel syndrome. This happens because the tunnel is too narrow, with very little soft tissue to protect it. The condition causes tingling, burning, forearm aches, or numbness in the forearm. Carpal tunnel syndrome, on the other hand, occurs in the wrist region. It involves the median nerve being trapped, and your thumb, index finger, and long finger are affected.
