Are you experiencing numbness, tingling, or weakness in your ring and pinky fingers? Do you feel an aching pain on the inside of your elbow? These are the classic signs of Cubital Tunnel Syndrome. You might hear doctors call it “ulnar neuritis” or “ulnar neuropathy,” but it simply means your ulnar nerve is under pressure. It is actually the second most common nerve pinch in the upper body, right after Carpal Tunnel Syndrome.

It happens when your ulnar nerve—which travels through a snug passage on the inside of your elbow called the cubital tunnel—gets squeezed, irritated, or stretched. If you leave it alone, Cubital Tunnel Syndrome can lead to ongoing discomfort, a loss of feeling, and even serious long-term issues like muscle weakness and permanent hand problems. At Hand Therapy, we focus on helping you understand and overcome this condition, guiding you toward lasting relief and getting your hand function back.

At the heart of this issue is your ulnar nerve. Think of this nerve as a long electrical wire that starts in your neck and runs all the way down to your fingertips. As it passes your elbow, it has to navigate through a very tight passage called the cubital tunnel.

Think of the cubital tunnel like a narrow hallway with very specific walls:
The Roof: This is made of a muscle and a band of tissue (Osborne’s ligament). This “ceiling” helps keep the nerve in place.
The Floor: This is the elbow joint itself and its supporting ligaments.
The Inner Wall: This is the prominent bony bump you can feel on the inside of your elbow (the medial epicondyle).
The Outer Wall: A part of your forearm bone (the olecranon).
Because this “hallway” is so narrow and sits right against the bone, the nerve is very vulnerable. This is why hitting your “funny bone” hurts so much—there is almost no padding protecting the nerve there!

Your ulnar nerve is a mixed nerve, which means it acts as both a power cable for movement and a sensor for feeling.

Motor Function (Movement)
In your forearm, it helps you bend your wrist. In your hand, it acts like a main controller for almost all the small, intricate muscles that let you do fine tasks.

It allows you to:

• Bend and straighten your pinky and ring fingers.
• Spread your fingers apart (like saying “high five”) and bring them back together.
• Pinch and grip objects tightly.
• Perform delicate tasks like writing, buttoning your shirt, or playing an instrument.

Sensory Function (Feeling)
The ulnar nerve provides sensation to:

• Your entire pinky finger.
• The half of your ring finger closest to the pinky.
• The edge of your palm and the back of your hand on that same side.

When the nerve gets squeezed in the tunnel, the electrical signals get fuzzy or cut off, leading to the symptoms you are feeling.

Cubital Tunnel Syndrome usually develops because of mechanical stress on the nerve. Imagine a garden hose; if you kink it, stretch it, or step on it, the water stops flowing. Your nerves work the same way.

Common Mechanical Causes:
Repetitive Elbow Bending (Kinking the nerve): When you bend your elbow past 90 degrees, the tunnel narrows and the nerve stretches. If you do this often, like holding a phone to your ear for hours or sleeping with your arms tucked in towards your chest or under your pillow, you are constantly kinking the hose.
Direct Pressure (Stepping on the nerve): Do you lean your elbow on a hard desk or a car armrest while driving? This “steps on” the nerve, compressing it against the bone.
Nerve Snapping: In some people, the nerve actually “pops” over the bony bump when they bend their arm. This constant snapping back and forth causes the nerve to become red and swollen.
Traction (Stretching the nerve): If your arm has a natural outward angle or if you are a throwing athlete (like a fast bowler in cricket), the nerve can stay under a constant “stretch.”

Other Contributing Factors:
Anatomical Variations: You might have naturally thicker tissues or extra muscle fibres in that area that crowd the tunnel.
Bone Spurs and Arthritis: “Wear and tear” in your elbow can create tiny bone bumps (spurs) that poke into the tunnel space.
Previous Trauma: Old fractures or dislocations can leave behind scar tissue or shifted bones that squeeze the nerve years later.
Health Conditions: Diabetes and obesity can make your nerves more sensitive to pressure.
Work & Play: Jobs involving manual labor, long hours of typing and mouse work, or sports like javelin, cricket and tennis put you at higher risk.

The symptoms usually show up in two ways: what you feel (sensory) and how you move (motor).

Sensory Symptoms

• Pins and Needles: This is the most common sign. It feels like your hand or fingers have “fallen asleep.” It hits your pinky and half of your ring finger.
• The “Night Shift”: Your symptoms feel worse at night because most of us naturally curl our elbows while we sleep.
• Pain: You might feel a dull ache on the inside of your elbow that shoots down toward your wrist. It can feel like an electric shock or a burning sensation.

Motor Symptoms

• Hand Weakness: You might notice you are clumsier. You might drop things, struggle to open jars, or find it hard to type or button your clothes.
• Muscle Wasting: In serious cases, the muscles in your hand can actually start to shrink. If you look at the web space between your thumb and index finger and see a hollow dip, that is a sign of muscle loss.
• The “Claw”: In very advanced cases, your ring and pinky fingers might start to curl up permanently into a “claw” shape.

This isn’t just a “annoying tingle.” Because it affects approximately 21 out of every 100,000 people every year, we know exactly how it progresses.
If you are over 40, you are at a higher risk for more severe nerve damage. The condition moves from Mild (occasional tingling) to Moderate (weakness you can measure) to Severe (constant numbness and visible muscle shrinking). If you ignore it, the damage to the nerve’s protective coating—or the nerve fibers themselves—can become permanent.

We are experienced in testing the different types of problems that can cause your elbow and nerve pain. Our specialists will assess your condition using a variety of nerve gliding, neural tissue mobilisation and standardised testing to determine the extent of the damage on the ulnar nerve. We will also be taking a detailed history to understand when your pain began and what activities, such as work or sleep, aggravate your symptoms. Following this, a physical exam will be conducted to evaluate your muscle strength, check for any muscle wasting (shrinking), and test your nerve sensation using specialised tools. This allows us to get a full picture of what is happening and how we can help you. If we feel that any other specialised testing is indicated, we can refer you.

Electromyography (EMG) and Nerve Conduction Studies (NCS)

These are the most informative tests for confirming nerve compression. It assesses the severity, and pinpointing the exact location of the compression. They measure how well electrical signals travel through your nerves and how your muscles respond. These tests can tell the difference between milder nerve irritation and more severe nerve damage, which impacts your prognosis.

X-rays
Used to identify any underlying bony problems, such as bone spurs, arthritis, or old fractures, that might be squeezing the nerve. This is however not the first choice of tests for this condition.

Ultrasound (High-frequency neuro-ultrasonography)

Ultrasound can visualise the ulnar nerve in real-time, showing changes in its size and position at the elbow, including its movement when the elbow is bent. This imaging is useful for pinpointing nerve compression in a specific area, provided the clinician knows where to focus the examination.

If you’ve been resting but your pain persists, it’s usually because the nerve hasn’t had a chance to truly “breathe.”

• Constant Irritation: Even small daily habits, like leaning on a desk, keep the nerve inflamed.
• Sheath Damage: The insulation around your nerve might be damaged, which takes a long time to repair.
• Delayed Treatment: The longer a nerve is squashed, the harder it is to “wake it up.”

The biggest danger is thinking this is “just a funny bone” issue. Because the symptoms come and go at first, many people wait until they see their muscles shrinking before seeking help. By that point, the damage is much harder to fix. Early intervention is the key to saving your hand function.

Occupational Therapy is the “secret weapon” for nerve issues. We don’t just give you exercises; we look at how you live your life.

• Ergonomic Training: We help you rearrange your desk and your habits to stop the pinching.
• Custom Splinting: We can make or recommend a lightweight “night splint” that keeps your elbow at a comfortable 45-degree angle so the nerve can rest while you sleep.
• Nerve Gliding: These are “stretches” for your nerve. We teach you how to gently slide the nerve through the tunnel to improve blood flow and reduce scarring.
• Strengthening: Once the nerve is happy, we help you rebuild the grip and pinch strength you may have lost.

Early Phase:

• Pain management in the inflammatory phase
• Reduce the swelling in and around the Carpal Tunnel
• Prevent and stop the regression of the damage on the nerve
• Reduce scar formation after the surgery

Intermediate Phase:

• Achieve pain free range of motion
• Improve sensation in the fingertips
• Functionality in light activities of daily living
• Modifying activities that increase the symptoms (ergonomics)

Rehabilitation Phase:

• Regain full active and passive range of motion
• Regain full grip strength
• Regain full fine motor coordination and control tasks such as fastening buttons and writing
• Regain full pain free functional use of hand

In most cases, Cubital Tunnel Syndrome responds very well when caught early, and you can typically expect your recovery to take between 4 to 6 weeks.

The time it takes for your hand to feel normal again is directly linked to how long you have been experiencing your symptoms. As a general rule, the longer your nerve has been squeezed without treatment, the longer the recovery journey will be. In my professional experience, nerves are some of the slowest-healing tissues in the body. Because they heal at such a gradual pace, starting your therapeutic process as soon as possible is the best way to ensure a full and speedy recovery for your hand.

If 3 to 6 months of therapy doesn’t help, or if your hand is getting weaker, surgery might be the next step. The goal is simple: Give the nerve more room.

• Decompression: The surgeon “opens the roof” of the tunnel to create more space.
• Transposition: The surgeon moves the nerve to the front of your elbow so it doesn’t get stretched when you bend your arm.
• Medial Epicondylectomy: The surgeon removes a small part of the bony bump to clear the path.

Surgery is usually an outpatient “day” procedure, and therapy is essential afterward to get your movement back.

• Ulnar Nerve Entrapment at the Elbow
• Ulnar Neuritis
• Cell Phone Elbow
• Funny Bone Nerve Compression

Not all hand tingling is Cubital Tunnel Syndrome. It could also be:

• Ulnar Tunnel Syndrome: A pinch at your wrist instead of your elbow.
• Neck Issues: A pinched nerve in your neck (C8-T1) can feel identical in your hand.
• Thoracic Outlet: A pinch near your collarbone.
• Carpal Tunnel: This affects your thumb and middle fingers instead of the pinky.

A proper evaluation is the only way to know for sure which “wire” is crossed!
