The Science Behind the Funny Bone: Anatomy and Function


Can understanding the location of the funny bone and how pain can be managed after injury help expedite recovery and prevention for individuals who have hit their funny bone?

Elbow Funny Bone Nerve Injury

Behind the elbow is an area known as the “funny bone,” where the ulnar nerve has less tissue and bone protection. This is where part of the ulnar nerve passes around the back of the elbow. Because less tissue and bone protect the nerve in this area, taking a hit like bumping into something can cause an electric shock-like pain and a tingling sensation down the arm and to the outside fingers typical of an irritated nerve. Most injuries to the funny bone resolve quickly, and the pain disappears after a few seconds or minutes, but sometimes, an ulnar nerve injury can lead to more persistent symptoms.


The funny bone is not a bone but the ulnar nerve. The nerve runs down the arm, passing around the back of the elbow. (Dimitrova, A. et al., 2019) Because the ulnar nerve is on top of the elbow and there is very little fatty cushion, lightly bumping this spot can cause pain and tingling sensations down the forearm. Three bones comprise the junction of the elbow that include:

  • Humerus – arm bone
  • Ulna and radius – forearm bones

The humerus has a groove that protects and holds the ulnar nerve as it passes behind the joint. This is where the nerve can be injured or irritated when the nerve is hit or pinched against the end of the bone, causing the funny bone pain.

Electrical Pain Sensation

When hitting the ulnar nerve or funny bone where the ulnar nerve provides sensation, pain, and electrical/tingling sensations are experienced from the forearm to the outside fingers. This part of the arm and hand is called the ulnar nerve distribution. (American Academy of Orthopaedic Surgeons. 2024) The ulnar nerve provides sensation into most of the pinky finger and about half of the ring finger. Other nerves, including the median and radial nerve, supply sensation to the rest of the hand.


Usually, a sharp jolt to the elbow quickly resolves. Some recommendations to help symptoms improve faster include:

  • Shaking the forearm and hand out.
  • Straightening out and bending the elbow to stretch the nerve.
  • Decreasing mobility of the elbow.
  • Applying ice to the area.
  • Taking anti-inflammatory medications.

Treating Long-Lasting Pain

In rare circumstances, injuries to the ulnar nerve can cause more persistent symptoms, a condition known as cubital tunnel syndrome. Cubital tunnel syndrome can happen after an injury or from elbow overuse. Individuals with cubital tunnel syndrome may benefit from wearing a splint at night. Standard-sized splints can be ordered online, but most are fabricated by an occupational or hand therapist. If symptoms become more long-lasting, surgery may be recommended to relieve pressure and tension on the ulnar nerve (American Academy of Orthopaedic Surgeons, 2024). The procedure decompresses the nerve by relieving any tight constrictions around it and releasing them. In severe cases, the nerve is repositioned to an area that doesn’t place as much pressure on the nerve, known as an ulnar nerve transposition.
