Cubital tunnel syndrome (CuTS) is a condition caused by pressure on the ulnar nerve, the nerve that runs along the inner side of the elbow. If left untreated, CuTS can cause severe pain and even permanent nerve damage. It’s important to be aware of the signs and symptoms of CuTS so that you can seek treatment before the condition becomes worse.

What are the Signs that You Have Cubital Tunnel Syndrome?

Are you experiencing pain, numbness, and tingling in your elbow and hands? If so, you might be suffering from cubital tunnel syndrome. This condition is also known as ulnar nerve entrapment, and it involves compression of the ulnar nerve in the elbow. Cubital tunnel syndrome is the second most common type of nerve entrapment after carpal tunnel syndrome. A condition like this requires the attention of a hand specialist, as it can cause permanent damage. Here are some of the common symptoms of CuTS to look out for.

1. Pain and Tenderness in the Elbow

One of the most common symptoms of cubital tunnel syndrome is pain and tenderness in the elbow. This is usually a result of the nerve becoming compressed, causing it to become inflamed. This pain is often accompanied by a burning or tingling sensation. The pain you feel can range from a dull ache to sharp, stabbing sensations that worsen with movement.

2. Numbness and Tingling in the Arm

Ever felt a pins and needles sensation in your arm? That could be a sign of cubital tunnel syndrome. Numbness and tingling in the arm, especially in the ring and little fingers, are common symptoms of this condition. The tingling sensation may come and go, or it may be constant.

3. Weakness in the Hand and Fingers

CuTS can also cause weakness in the hand and fingers. This can range from a mild feeling of clumsiness to an inability to grip objects or make a fist. Weakness in the hand and fingers can make it difficult to do everyday tasks, such as buttoning a shirt or opening a jar. If you experience weakness in the hand or fingers, it is essential to seek medical attention.

4. Pain and Tenderness in the Neck

Cubital tunnel syndrome can cause pain and tenderness in the neck, as well as radiating pain down the arm. This is due to the compression of the ulnar nerve in the neck. Pain and tenderness in the neck can range from mild to severe and can even cause headaches if left untreated.

5. Swelling of the Elbow

In some cases, cubital tunnel syndrome can cause swelling of the elbow due to the increased pressure on the ulnar nerve. This swelling can be painful and can limit the range of motion of the elbow joint. If swelling persists, it is important to seek medical attention to prevent further damage to the nerve.


If you experience any of the symptoms associated with cubital tunnel syndrome, you should consult with your doctor. The condition can cause serious discomfort and limit movement in the affected area. The earlier the treatment is initiated, the better the chances of fully recovering. Even if the symptoms are not severe, it is always important to get an accurate diagnosis and treatment plan to prevent the condition from worsening.
