Causes of Right Shoulder Pain at Night

If you find yourself experiencing right shoulder pain at night, it can be both frustrating and disruptive to your sleep. Understanding the various causes of this pain can help you identify the underlying issue and seek appropriate treatment. Here are some common causes of right shoulder pain at night:

Causes and Treatment of Right Shoulder Pain at Night

Muscle strain or injury

Muscle strain or injury is a common cause of right shoulder pain at night. Overuse or repetitive motions, such as constantly lifting heavy objects or participating in activities that involve repetitive shoulder movements, can strain the muscles in your shoulder. Inadequate warm-up before physical activities can also increase the risk of muscle strain. Direct trauma or impact to the shoulder, such as from a fall or accident, can result in injury and subsequent pain. Muscle imbalances and poor posture can additionally contribute to shoulder strain and discomfort.

Rotator cuff tear

A rotator cuff tear refers to a tear in the group of tendons and muscles that surround the shoulder joint, providing stability and allowing for a wide range of motion. There are different types of rotator cuff tears, including degenerative tears that occur gradually over time, acute tears due to trauma or injury, and age-related tears. Rotator cuff tears often cause pain and can limit your ability to move the shoulder freely.

Shoulder impingement

Shoulder impingement occurs when the structures in the shoulder joint become compressed or irritated, resulting in pain. Repetitive overhead activities, such as throwing, swimming, or lifting weights, can contribute to shoulder impingement. Structural abnormalities in the shoulder joint, such as bone spurs or a hooked acromion, can also increase the risk of impingement. Muscle imbalances and poor posture can further exacerbate the problem. Inflammation and swelling are common symptoms associated with shoulder impingement.


Osteoarthritis is a degenerative joint disease that can affect the shoulder joint. Over time, the protective cartilage in the joint can wear away, leading to joint inflammation, pain, and limited range of motion. Age-related wear and tear are significant factors contributing to the development of osteoarthritis in the shoulder. As the condition progresses, it can cause significant discomfort, especially at night.

Bursitis refers to the inflammation of the fluid-filled sacs called bursae, which act as cushions between bones, tendons, and muscles in the shoulder joint. Shoulder joint overuse or trauma can lead to bursitis, causing pain and swelling in the affected area. This can be particularly bothersome at night, as the inflammation and pressure on the bursae can result in discomfort when lying down.

Frozen shoulder

Frozen shoulder, also known as adhesive capsulitis, is a condition characterized by inflammation and thickening of the shoulder capsule. This leads to a gradual loss of shoulder movement and flexibility, accompanied by pain and stiffness. The exact cause of frozen shoulder is not fully understood, but possible risk factors include diabetes, thyroid problems, and shoulder immobilization. The pain and limited mobility associated with frozen shoulder can make nighttime shoulder pain particularly troublesome.


Tendonitis refers to the inflammation and irritation of the shoulder tendons, which are thick bands of tissue that connect muscles to bones. Repetitive motions or overuse of the shoulder joint, such as those involved in sports, can lead to tendonitis. Shoulder tendonitis typically causes pain, swelling, and difficulty moving the shoulder, which can be particularly pronounced at night.

Pinched nerve

A pinched nerve in the shoulder can occur when the surrounding tissues compress or put pressure on a nerve root. This can cause pain, tingling, numbness, or weakness in the shoulder and can extend down the arm. While pinched nerves can be caused by various factors, such as herniated discs or muscle impingement, they can contribute to nighttime shoulder pain.

Referred pain from other areas of the body

Sometimes, right shoulder pain at night may not originate directly from the shoulder itself but may instead be referred pain from other areas of the body. For example, conditions such as gallbladder disease, heart disease, or cervical spine issues can cause pain that radiates to the shoulder. Identifying the source of the referred pain is crucial for proper diagnosis and treatment.

Now that we have explored the various causes of right shoulder pain at night, let’s discuss some treatment options that can help alleviate your discomfort and improve your quality of sleep.
