If you’ve ever experienced the discomfort of waking up with upper arm pain, you know just how frustrating it can be. Whether it’s a dull ache or a sharp, shooting sensation, this type of pain can disrupt your sleep and leave you feeling groggy and irritable the next day. But what causes this upper arm pain when sleeping? In this article, we’ll explore the possible reasons behind this discomfort and offer some suggestions on how to alleviate it, so you can enjoy a peaceful night’s rest.

Causes of Upper Arm Pain When Sleeping

Do you often wake up with pain in your upper arm? If so, you’re not alone. Many people experience discomfort or even intense pain in their upper arm when they wake up from sleep. This can be a frustrating and disruptive experience, as it affects the quality of your rest and can make it difficult to carry out daily activities. In this article, we will explore some common causes of upper arm pain when sleeping and discuss possible treatment options.

Causes of Upper Arm Pain When Sleeping

Muscle strain

Muscle strain, also known as a pulled muscle, is one of the most common causes of upper arm pain when sleeping. This occurs when the muscles in your upper arm are stretched or torn due to overuse, sudden movements, or excessive force. If you have recently engaged in activities that involve repetitive arm motions or lifting heavy objects, you may have strained your muscles and are experiencing pain as a result.

Rotator cuff injury

The rotator cuff is a group of muscles and tendons that surround the shoulder joint, providing stability and allowing for a wide range of motion. When the rotator cuff becomes damaged or injured, it can lead to upper arm pain when sleeping. This type of injury is often caused by repetitive overuse, traumatic events such as falls or accidents, or degeneration due to aging. If you notice weakness, aching, or difficulty moving your arm, a rotator cuff injury may be the culprit.

Causes of Upper Arm Pain When Sleeping

Shoulder impingement syndrome

Shoulder impingement syndrome occurs when the space between the top of the shoulder blade and the upper arm becomes narrowed, resulting in the compression of tendons and other structures. This compression can cause pain in the upper arm, especially at night when lying on the affected side. Common causes of shoulder impingement syndrome include repetitive overhead activities, poor posture, and muscle imbalances.

Frozen shoulder

Frozen shoulder, also known as adhesive capsulitis, is a condition characterized by stiffness and pain in the shoulder joint. While the primary symptom is shoulder pain, this discomfort can radiate down the upper arm and contribute to sleep disturbances. Frozen shoulder often occurs due to injury, underlying medical conditions such as diabetes or thyroid disorders, or as a result of immobilization of the shoulder joint.

Causes of Upper Arm Pain When Sleeping

Shoulder bursitis

The bursae are fluid-filled sacs that act as cushions between bones, tendons, and muscles. When the bursae become inflamed, a condition known as bursitis, it can lead to upper arm pain when sleeping. Shoulder bursitis is often caused by repetitive motions or direct trauma to the shoulder joint. If you experience tenderness, swelling, or aching in the upper arm, bursitis may be the cause.


Tendons are thick cords that connect muscles to bones. When these tendons become inflamed or irritated, it is called tendinitis. Tendinitis can occur in the upper arm, particularly in the tendons surrounding the shoulder joint. Overuse or repetitive motions, such as throwing a ball or lifting weights, can contribute to tendinitis and result in discomfort or pain when sleeping.


Arthritis is a common condition that causes joint inflammation and pain. While most commonly associated with the hands, knees, and hips, arthritis can also affect the shoulder joint and contribute to upper arm pain when sleeping. Osteoarthritis, which occurs due to wear and tear on the joints, and rheumatoid arthritis, an autoimmune disease, are two types of arthritis that can impact the shoulder and result in nighttime discomfort.

Carpal tunnel syndrome

Although carpal tunnel syndrome primarily affects the wrist and hand, it can also lead to referred pain in the upper arm. Carpal tunnel syndrome occurs when the median nerve, which runs through the wrist, becomes compressed or pinched. This compression can cause pain, tingling, or numbness that radiates up the arm and may worsen at night. If you frequently engage in activities that involve repetitive wrist movements, such as typing or playing an instrument, carpal tunnel syndrome might be a potential cause of your upper arm pain when sleeping.

Pinched nerve

A pinched nerve, also known as nerve compression, occurs when surrounding tissues or structures apply pressure to a nerve. When a nerve in the neck or shoulder area becomes pinched, it can cause pain that radiates down the arm, leading to discomfort when you are trying to sleep. Poor posture, herniated discs, or bony growths on the spine can contribute to nerve compression and result in upper arm pain.

Heart-related issues

While upper arm pain when sleeping is often related to musculoskeletal problems, it is essential to consider the potential involvement of the heart. In some cases, upper arm pain can be a referred symptom of a heart condition, such as angina or a heart attack. If you experience persistent or severe upper arm pain, especially if accompanied by shortness of breath, chest pain, or dizziness, it is crucial to seek immediate medical attention.

In conclusion, upper arm pain when sleeping can significantly impact your well-being and daily activities. By understanding the potential causes of this discomfort, you can work with healthcare professionals to identify the underlying issue and develop an appropriate treatment plan. Whether it be muscle strain, rotator cuff injuries, shoulder impingement, or other factors, addressing the root cause of your upper arm pain can help you find relief and regain restful nights. Remember to consult with a healthcare provider for an accurate diagnosis and personalized recommendations based on your specific situation. Sleep well and address your upper arm pain to improve your overall quality of life.
