What Are the Symptoms of Nerve Damage in the Shoulder?

Shoulder pain, tingling, numbness, and weakness in the arm are common signs of nerve damage. You may also notice reduced muscle strength and difficulty lifting your arm. These symptoms often result from nerve compression, a brachial plexus injury, or damage to the axillary nerve.

At Total Orthopedics & Sports Medicine, we specialize in diagnosing and treating shoulder nerve pain caused by compression, injury, or repetitive strain. Our specialists use ultrasound-guided assessments and regenerative therapies to identify the source of irritation and promote healing at the cellular level.

Is Shoulder Pain a Sign of Nerve Damage?

Yes, shoulder pain can be a sign of nerve damage, especially when it is accompanied by numbness, muscle weakness, or electric-shock sensations. These symptoms develop when nerves in the neck, shoulder, or brachial plexus get compressed or injured. In many cases, nerve irritation results from underlying conditions, such as a herniated disc or traumatic injuries like fractures and dislocations, which affect nerve pathways.

Moreover, cervical radiculopathy is the most common cause of shoulder and neck pain. According to the NICE Clinical Knowledge Summaries, cervical radiculopathy affects between 121 and 580 people per 100,000 each year, often leading to pain, numbness, and weakness that extend from the neck into the shoulder and arm.

Can Reflex Changes Or Sensory Loss Indicate Shoulder Nerve Injury?

Yes, changes in your reflexes or sensation can indicate a shoulder nerve injury. These reflex or sensory changes happen when the brachial plexus, axillary, suprascapular, or long thoracic nerves are damaged, which disturbs normal communication between your brain and shoulder muscles. As a result, you may experience tingling, numbness, or weakness in your shoulder and arm.

In addition to reflex changes, the location of sensory loss can help your doctor identify which shoulder nerve is affected. For example, axillary nerve injury may cause numbness over the deltoid muscle, while injury to the suprascapular nerve often leads to pain or tingling near the shoulder blade. To confirm these symptoms and assess nerve function, doctors often use electromyography (EMG) and magnetic resonance imaging (MRI). These advanced diagnostic tests can detect nerve injury in its early stages.

Why Does Shoulder Nerve Pain Get Worse at Night?

Shoulder nerve pain often gets worse at night because lying down increases pressure on already irritated nerves. As your body remains in one position for hours, blood flow slows and the surrounding muscles tighten, which further compresses the affected area. As a result, inflammation and nerve sensitivity increase, leading to sharper pain and greater discomfort during rest.

Certain conditions can also worsen the shoulder pain at night. For example, shoulder impingement syndrome (which occurs when tendons or bursae are compressed under the shoulder blade) often causes discomfort during rest.

According to the University of Maryland Medical Center, shoulder impingement syndrome accounts for 44% to 65% of all shoulder complaints. This condition often causes more pain at night, especially when lying on the affected side. Similarly, rotator cuff injuries or tendonitis can also worsen nerve inflammation during sleep.

What Causes Nerve Damage in the Shoulder?

Nerve damage in your shoulder usually develops when the nerves are stretched, compressed, or injured due to trauma, repetitive strain, or underlying conditions like a herniated disc or diabetes. It can also result from sports injuries, poor posture, or prolonged pressure on the shoulder joint.

Other common causes of shoulder nerve damage include:

• Rotator cuff tears: Injury to surrounding muscles or tendons can place extra pressure on nearby nerves, causing irritation and pain.
• Bone spurs: These bony growths can compress the nerves surrounding the joint, causing sharp, radiating pain.
• Shoulder dislocation: When the joint shifts out of place, it can stretch or pinch the nerves, which results in numbness.
• Repetitive strain injury (RSI): Continuous overhead movement, lifting, or throwing can cause inflammation and damage to shoulder nerves over time.

Are Sports Injuries a Major Cause of Shoulder Nerve Damage?

Yes, sports injuries can cause shoulder nerve damage, especially if you participate in activities that involve repetitive overhead motion or direct impact. Sports such as baseball, tennis, swimming, and weightlifting place extra stress on your shoulder, which can stretch or compress the surrounding nerves. 

Over time, these repetitive or high-impact movements can injure your brachial plexus or axillary nerve, which leads to pain, tingling, or weakness that radiates from your shoulder into your arm. In many athletes, this nerve damage develops gradually due to overuse or poor technique rather than a single traumatic event. 

However, contact sports such as football can cause sudden traction injuries to the brachial plexus, commonly known as a “stinger.” According to the Orthopaedic Journal of Sports Medicine, NFL players experienced an average of 138 stinger injuries per year between 2015 and 2019, affecting about 3.7% of players each season. Therefore, recognizing these risks early can help prevent long-term shoulder weakness and support a safe recovery.

Can Nerve Damage In The Shoulder Heal On Its Own?

Yes, shoulder nerve injuries can recover naturally, depending on their severity. Mild pinched nerves from poor posture or repetitive motion often recover with rest, gentle stretching, and nonsurgical treatment. However, severe nerve injuries may not recover without medical treatment.

For example, axonotmesis (a condition where nerve fibers are damaged but the connective tissue remains intact) can sometimes heal with conservative care over 3 to 4 months. But if recovery does not occur within six months, doctors may recommend surgery to restore proper nerve function.

What Surgical Procedures Are Used to Repair Shoulder Nerve Damage?

Surgeons most commonly perform nerve grafting, nerve transfer, and decompression surgery to repair nerve damage in the shoulder. These surgeries restore communication between the spinal cord or peripheral nerves and the shoulder muscles, which helps reduce nerve pain, improve muscle strength, and regain arm function.

In addition, surgeons may use other specialized procedures to restore shoulder function, such as:

• Neurolysis: Removes scar tissue around compressed nerves to restore normal function.
• Spinal accessory nerve repair: Reconnects or reconstructs the spinal accessory nerve to restore trapezius strength and shoulder movement.
• Free functional muscle transfer: Transplants healthy muscle with its nerve to replace a paralyzed muscle and regain motion.
• Internal neurolysis with nerve wrapping: Carefully separates the nerve from surrounding tissue and wraps it to prevent scar formation.
• Quadrilateral space decompression: Relieves nerve entrapment in the quadrilateral space to restore signal transmission and reduce pain.

Can TENS Therapy Help Repair Damaged Shoulder Nerves?

No, TENS therapy cannot directly repair damaged shoulder nerves, but it can help reduce pain and support your shoulder recovery. By delivering low-voltage electrical currents through the skin, TENS stimulates nerves and muscles, which helps reduce inflammation, improve circulation, and decrease shoulder nerve pain.

According to a systematic review of 381 randomized controlled trials published in BMJ Open, TENS therapy significantly reduced the intensity of musculoskeletal pain during or immediately after treatment compared with a placebo. When used consistently under medical supervision, TENS therapy can effectively ease discomfort and help restore shoulder strength and function.

At Total Orthopedics & Sports Medicine, we support TENS therapy with targeted exercises and appropriate pain relief to promote recovery from nerve injuries. Book your consultation today.

How Can Occupational Therapy Help with Shoulder Nerve Damage?

Occupational therapy plays an essential role in restoring shoulder strength and function after nerve damage. It focuses on retraining the muscles and movements affected by the nerve injury, which helps you regain stability and coordination.

Additionally, occupational therapy employs advanced techniques that promote nerve healing and enhance mobility. Treatment often begins with sensory re-education, where your doctor applies specialized sensory techniques involving touch and temperature to retrain damaged nerves and restore normal sensation.

As strength improves, your doctor may introduce resistance band exercises and controlled stretching to build endurance and maintain flexibility. In the later stages, mirror therapy and mental imagery techniques are often used to improve nerve communication and strengthen shoulder and arm movements for smoother coordination.
