Cubital Tunnel Syndrome Pain & Treatment

Cubital tunnel syndrome happens when the ulnar nerve — the same nerve behind your “funny bone” — gets compressed or irritated at the inner elbow. It causes tingling, numbness, and weakness in the hand, and catching it early matters. Our orthopedic and sports medicine team treats it across Long Island and northern New Jersey, with offices in Plainview, New Hyde Park, and Ronkonkoma, NY, and Clifton, Montville, and Plainfield, NJ.

What cubital tunnel syndrome is

The ulnar nerve runs along the inside of your elbow through a narrow passage called the cubital tunnel. When it’s compressed or stretched there — often from leaning on the elbow, keeping it bent for long periods, or repetitive bending — it can’t send signals properly. That produces tingling, numbness, and eventually weakness in the parts of the hand the nerve supplies.

It’s a nerve problem, not a tendon problem, which is why it’s treated differently from tennis or golfer’s elbow. Classic symptoms include tingling or numbness in the ring and little fingers, pain on the inner elbow, a weakening grip, and symptoms that flare when the elbow is bent — such as while holding a phone or sleeping.

How cubital tunnel syndrome is treated

Treatment depends on how severe the compression is and whether there’s muscle weakness:

• Activity changes — avoiding leaning on the elbow and reducing prolonged or repeated elbow bending.
• Bracing or night splinting — keeping the elbow from bending too much, especially during sleep, is often very effective for milder cases.
• Physical therapy — nerve-gliding exercises and activity guidance can help.
• Surgical release — if symptoms persist, worsen, or there’s muscle weakness or wasting, a procedure to relieve pressure on the ulnar nerve may be recommended.

Related conditions

Cubital tunnel is a nerve-compression problem, closely related to carpal tunnel syndrome (which compresses a different nerve at the wrist). If your elbow pain is tendon-related instead, see our tennis elbow and golfer’s elbow pages, or return to our elbow pain overview.

Frequently asked questions

What does cubital tunnel syndrome feel like?

Tingling or numbness in the ring and little fingers, pain on the inner elbow, and a weakening grip. Symptoms often flare when the elbow is bent, such as when holding a phone or sleeping.

How is it different from carpal tunnel?

Both are nerve compressions, but in different places: cubital tunnel compresses the ulnar nerve at the elbow (ring and little fingers), while carpal tunnel compresses the median nerve at the wrist (thumb, index, and middle fingers).

Can cubital tunnel syndrome heal without surgery?

Mild cases often improve with activity changes and night splinting to keep the elbow from bending too much. Surgery is considered when symptoms persist, worsen, or there’s muscle weakness.

Why are my symptoms worse at night?

Many people sleep with the elbow bent, which stretches and compresses the ulnar nerve. A night splint that keeps the elbow straighter often helps significantly.

What happens if it’s left untreated?

Ongoing compression can lead to lasting weakness or muscle wasting in the hand. That’s why persistent numbness or a weakening grip should be evaluated promptly.

How is it diagnosed?

Through your history, a physical exam, and often a nerve conduction study to measure how well the ulnar nerve is working and how severe the compression is.
