Y'all Asked: Why does it hurt when y'all hit your funny os?
Anything but humerus (pun intended), don't get on the funny os's nerves

If you hit your elbow just right, chances are you'll suddenly feel a abrupt pain and unpleasant prickling sensation radiate down your arm. You may fifty-fifty exclaim a few pick words nigh your situation out of sheer agony and surprise. Information technology's true: A knock to the 'funny os' is anything only funny.
Surprisingly, the funny os isn't really a os at all. Information technology's really a cluster of nerves called the ulnar nerve—a bundle of sensitive fibers that run backside your elbow articulation. The ulnar nervus starts in the spine and offshoots through the shoulder and down the arm, ending in both the pinky finger and ring finger. It then follows a delicate pathway that is unprotected equally information technology passes backside the knob of the elbow.
"The ulnar nerve is wedged between the bone and the peel near the elbow joint with little to no cushion or protection," said Cody Bruce, MSN, RN, assistant professor with the Texas A&M Health Scientific discipline Heart College of Nursing. "When your elbow is extended, this area is protected, but, if the elbow is bent, it opens upwardly this sensitive expanse. When you hit that groove, y'all're actually pinching the nervus, which is why y'all experience moderate discomfort and a tingling feeling down the arm."
Co-ordinate to the American University of Orthopedic Surgeons, the ulnar nervus controls most of the small muscles in the paw and wrist that coordinate fine movements, plays a cardinal function in function and coordination, and is responsible for delivering sensation to the pinky and ring fingers while directing the bigger forearm muscles to help in grip strength.
Sometimes funny os hurting can be more serious than simply striking your elbow at the wrong angle. Persistent discomfort may signal a chronic health condition called "cubital tunnel syndrome," which happens when the ulnar nerve is subjected to constant pressure or stretching.
Direct pressure (similar flattening the arm against a desk or arm rest) tin squash the ulnar nerve resulting in a pins-and-needles sensation, as if the hand or arm has fallen "comatose." Keeping the elbow bent for extended periods of time may besides stretch the nerve—most common when nosotros stay in one positon during sleep. Repeating snapping of the elbow (routine in sports like tennis and golf) is another culprit.
"Cubital tunnel syndrome shouldn't exist confused with carpal tunnel syndrome (which primarily affects the wrist)," Bruce said. "Symptoms of cubital tunnel syndrome include pain, loss of sensation, tingling and weakness—normally bars to the ring and pocket-size fingers. Texting has actually increased diagnosis of cubital tunnel syndrome in contempo years because the arm stays in a fixed, aptitude position when people text."
Bruce said cubital tunnel syndrome unremarkably affects the ascendant arm, and if your arm or fingers get numb or tingly while texting, or in a aptitude position, you should straighten your arm out to bring claret flow and circulation back to the surface area. If the uncomfortable feeling persists, you may need to consult with your health care provider for treatment options.
Through history, it'south nonetheless unclear as to how the ulnar nervus was dubbed the funny os. Bruce said one reason the name stuck is considering of the boring tingling or funny sensation that occurs when the expanse is irritated. Others believe information technology's a play on words, since the upper arm bone that runs between the elbow and shoulder is called the humerus. "One thing is clear: The funniest thing near the funny os is information technology's the but 'os' in the trunk you can't intermission, because it's a nerve," Bruce said.
