Have you ever experienced a strange tingling or numbness in your ring and little fingers, especially at night or when your elbow is bent for a long time? If yes, you might be suffering from Cubital Tunnel Syndrome — a common but often overlooked cause of night-time elbow discomfort.
This article explains why your elbow tingles at night, what causes Cubital Tunnel Syndrome, its symptoms, diagnosis, treatment options, and how you can prevent it from worsening.
This blog is authored for Dr. Vishal Sahni (MBBS, MS Ortho, FRCS Ortho, London, MCH Ortho, Liverpool) — a highly experienced Orthopaedic Surgeon and Shoulder, Elbow, and Wrist Specialist at London Orthopaedic Clinic, Dhantoli, Nagpur. With over two decades of orthopaedic experience in London and India, Dr. Sahni is known for advanced, patient-focused treatment for complex upper limb conditions.
What is Cubital Tunnel Syndrome?
Cubital Tunnel Syndrome occurs when the ulnar nerve — one of the main nerves running down your arm — becomes compressed or irritated as it passes through a narrow space on the inside of your elbow called the cubital tunnel.
The ulnar nerve controls sensation in your ring and little fingers, and also helps in hand grip and fine motor control. When this nerve gets compressed at the elbow, it can cause tingling, numbness, weakness, and sometimes even pain, especially noticeable at night or when you keep your elbow bent for a long time.
In simple words, Cubital Tunnel Syndrome is like “a traffic jam in your nerve pathway” — where the signals from your brain to your hand are slowed or blocked.
Why Does the Tingling Happen at Night?
You might wonder, “Why does my elbow only tingle when I go to sleep?”
The reason lies in how you position your arm at night. Many people naturally sleep with their elbows bent or rest their head on a bent arm. This bending stretches and compresses the ulnar nerve inside the cubital tunnel.
During the day, you might also bend your elbow frequently — while using your phone, typing, or driving — which further irritates the nerve. But when you sleep, the problem worsens because your body remains in that bent position for hours, causing the nerve to get irritated continuously.
This leads to night-time tingling, numbness, or a “pins and needles” feeling in the fingers — a classic sign of Cubital Tunnel Syndrome.
Common Causes of Cubital Tunnel Syndrome
There isn’t always a single cause, but several factors may contribute to the compression of the ulnar nerve:
1. Frequent Elbow Bending
Activities that involve repeated elbow flexion — such as holding a phone, resting elbows on hard surfaces, or typing for long hours — can stretch and irritate the ulnar nerve.
2. Direct Pressure on the Elbow
Leaning on your elbows while sitting at a desk or driving can compress the nerve, especially on hard surfaces. This habit can easily develop into nerve irritation over time.
3. Anatomical Variations
Some people have a naturally narrow cubital tunnel or soft tissue thickening around the nerve that increases friction and pressure.
4. Previous Elbow Injury
A fracture, dislocation, or arthritis around the elbow joint can alter bone alignment and narrow the nerve space, making compression more likely.
5. Repetitive Strain and Occupational Causes
Jobs or sports that require repetitive elbow movement — such as carpentry, weightlifting, or computer work — increase the risk of developing this condition.
6. Diabetes or Thyroid Problems
In certain systemic conditions, nerves become more sensitive to compression, making individuals more prone to Cubital Tunnel Syndrome.
Key Symptoms to Watch For
Cubital Tunnel Syndrome develops gradually. Early detection can help prevent permanent nerve damage. Look for these telltale signs:
1. Numbness and Tingling
The most common symptom is tingling or numbness in the ring and little fingers. Initially, it comes and goes, but as the condition worsens, it may persist throughout the day.
2. Night-time Discomfort
Tingling or burning sensations often increase at night when you sleep with bent elbows. Some people even wake up due to discomfort.
3. Weak Grip Strength
As the nerve compression increases, the muscles controlling your hand grip may weaken, making it hard to hold objects or perform fine movements.
4. Hand Muscle Wasting
In chronic or untreated cases, you may notice muscle wasting between the thumb and index finger, giving your hand a thin appearance.
5. Elbow Pain or Soreness
Some people experience aching pain on the inner side of the elbow, especially when bending or resting the elbow for long periods.
If you’re experiencing these symptoms, it’s best to consult an Orthopaedic Doctor in Nagpur who specialises in Elbow and Nerve-related Disorders like Dr. Vishal Sahni for a proper diagnosis and treatment plan.
How is Cubital Tunnel Syndrome Diagnosed?
Diagnosis starts with a detailed clinical evaluation and may include nerve function tests to assess the severity.
1. Physical Examination
Dr. Vishal Sahni will check for numbness, tingling, or weakness by gently tapping the area over the ulnar nerve (Tinel’s sign) and may assess your elbow range of motion and grip strength.
2. Nerve Conduction Study (NCS)
This test measures how quickly electrical signals travel through the ulnar nerve. Slow signal speed indicates compression.
3. Electromyography (EMG)
EMG checks the electrical activity of muscles to detect any nerve or muscle damage.
4. Ultrasound or MRI
Imaging helps visualise the cubital tunnel anatomy, ruling out other causes like cysts, bone spurs, or structural abnormalities.
Treatment Options for Cubital Tunnel Syndrome
Treatment depends on the severity of symptoms. The goal is to relieve pressure on the ulnar nerve and restore normal function.
1. Lifestyle Modifications
For mild cases, simple changes in daily habits can bring major relief:
- Avoid resting elbows on hard surfaces.
- Use a soft elbow pad while working or sleeping.
- Keep your elbow straight during sleep by wrapping it loosely with a towel.
- Take frequent breaks if your job involves repetitive elbow movements.
2. Physiotherapy
Stretching and nerve gliding exercises prescribed by your orthopaedic doctor help reduce stiffness and improve nerve mobility. Strengthening the forearm and hand muscles can prevent further strain.
3. Medications
Anti-inflammatory medications may help relieve pain and reduce swelling around the nerve. However, they only provide temporary relief and do not correct the underlying cause.
4. Splinting or Night Braces
Wearing a splint at night keeps your elbow in a slightly straight position, preventing excessive bending that compresses the ulnar nerve.
5. Occupational Therapy
For individuals whose work habits contribute to the problem, ergonomic adjustments like changing desk height, using cushioned armrests, or modifying repetitive tasks can help reduce pressure on the elbow.
When is Surgery Needed?
If non-surgical treatments do not relieve symptoms or if nerve compression is severe, surgery may be recommended.
Dr. Vishal Sahni, a highly skilled Orthopaedic and Shoulder-Elbow-Wrist Surgeon in Nagpur, performs advanced elbow decompression surgeries to release the trapped ulnar nerve safely and effectively.
Surgical Options Include:
1. Simple Decompression
The surgeon enlarges the cubital tunnel by removing the pressure on the ulnar nerve, allowing it to glide freely.
2. Ulnar Nerve Transposition
If the nerve tends to slip out of its position or remains under tension, it is carefully moved to the front of the elbow, away from the bony area.
3. Medial Epicondylectomy
A small portion of bone on the inner side of the elbow is removed to relieve pressure.
Each procedure is chosen based on the patient’s anatomy, activity level, and the severity of nerve compression.
Modern surgical techniques allow for faster recovery, minimal scarring, and lasting relief from symptoms.
Recovery and Post-Surgery Care
Recovery depends on the extent of nerve damage and the type of surgery performed. Typically, patients can expect:
- Pain relief and improved sensation within weeks.
- Return of muscle strength in a few months.
- Physical therapy to restore flexibility and strength.
After surgery, Dr. Vishal Sahni and his team at the London Orthopaedic Clinic, Nagpur, guide patients through a personalised rehabilitation programme, ensuring safe and complete recovery.
Patients are advised to:
- Avoid lifting heavy weights for a few weeks.
- Perform gentle elbow and hand movements as instructed.
- Follow regular follow-up visits to monitor nerve healing.
Self-Care Tips and Prevention
Even after recovery, maintaining good elbow health is important. Here are practical tips you can follow daily:
- Avoid Prolonged Elbow Bending – Keep your arm straight when possible, especially during sleep or long phone calls.
- Use Ergonomic Support – A well-designed workspace with cushioned armrests helps prevent compression.
- Exercise Regularly – Gentle stretching and strengthening exercises for your arms and hands can improve flexibility.
- Watch for Warning Signs – Early tingling or weakness should not be ignored. Seek expert advice before it worsens.
- Take Breaks During Work – Short breaks while typing or driving help reduce strain on the elbow joint.
Why Early Treatment Matters
Delaying treatment for Cubital Tunnel Syndrome can lead to permanent nerve damage. Once the ulnar nerve becomes severely compressed, even surgery might not fully restore its function.
Early diagnosis by an experienced Elbow Specialist in Nagpur, such as Dr. Vishal Sahni, helps prevent complications and ensures better outcomes. The sooner you act, the easier it is to reverse symptoms and protect hand function.
