This mysterious discomfort, known as shoulder pain upon waking up, can be quite a nuisance, hampering your ability to start the day on the right foot. In this article, we will explore the various causes of this frustrating phenomenon, shedding light on possible culprits and providing insights on how you can find relief. So, grab a cup of coffee and let’s unravel the mysteries behind why your shoulder might be giving you grief every morning.

Causes of Shoulder Pain Upon Waking Up

If you find yourself waking up with shoulder pain, you are not alone. Many people experience discomfort in their shoulders when they first wake up in the morning. This can be caused by a variety of factors, ranging from muscle imbalances to medical conditions. In this article, we will explore the different causes of shoulder pain upon waking up and provide you with a comprehensive understanding of each one.

Causes of Shoulder Pain Upon Waking Up

Muscle Imbalance

Muscle imbalances occur when certain muscles in your shoulder are either too weak or too tight in comparison to their opposing muscles. This can lead to improper movement and strain on the shoulder joint, resulting in pain. Inadequate stretching, muscle overuse or underuse, and weakness or tightness in specific muscles can all contribute to muscle imbalances in the shoulder.

Rotator Cuff Impingement

The rotator cuff is a group of muscles and tendons that help stabilize the shoulder joint. When these muscles and tendons become impinged or pinched between the bones of the shoulder, it can cause pain and discomfort. Repetitive overhead activities, poor posture, and muscle imbalances can all lead to rotator cuff impingement.

Frozen Shoulder

Frozen shoulder, also known as adhesive capsulitis, is a condition characterized by limited movement and stiffness in the shoulder joint. The exact cause of frozen shoulder is unknown, but it is believed to be related to inflammation and scarring of the joint capsule. People with diabetes, thyroid problems, and certain autoimmune conditions are more prone to developing frozen shoulder.


Bursitis occurs when the bursa, small fluid-filled sacs that cushion the bones, tendons, and muscles around the joints, become inflamed. This inflammation can cause pain in the shoulder joint. Bursitis can be caused by repetitive motions, such as throwing or lifting overhead, or by injury or infection.

Tendinitis is the inflammation of the tendons, which are the thick cords that attach muscles to bones. This inflammation can cause pain and limited mobility in the shoulder joint. Tendinitis can be caused by overuse or repetitive motions, as well as degeneration due to aging.


Arthritis refers to joint inflammation and pain. There are two common types of arthritis that can cause shoulder pain: osteoarthritis and rheumatoid arthritis. Osteoarthritis occurs when the cartilage that cushions the bones in the shoulder joint wears down over time, resulting in pain and stiffness. Rheumatoid arthritis is an autoimmune disorder that causes inflammation in the joints, including the shoulder.

Shoulder Instability

Shoulder instability occurs when the structures that surround the shoulder joint, such as the ligaments and tendons, are unable to keep the ball of the upper arm bone securely in the shoulder socket. This can result in a dislocated shoulder or a labral tear, where the cartilage that lines the socket is damaged. Shoulder instability can be caused by trauma or an underlying joint laxity.

Sleeping Position

The position in which you sleep can also contribute to shoulder pain upon waking up. Sleeping on one side for an extended period of time can put pressure on the shoulder joint and lead to discomfort. Similarly, sleeping with your arm over your head can cause strain on the shoulder muscles and tendons. Additionally, using an uncomfortable pillow or mattress that does not provide proper support can exacerbate shoulder pain.

Injury or Trauma

An injury or trauma to the shoulder, such as a fall or accident, can cause immediate or delayed onset of shoulder pain upon waking up. Damage to the muscles, tendons, ligaments, or bones in the shoulder can result in pain and limited mobility. It is important to seek medical attention if you have experienced a shoulder injury to ensure proper diagnosis and treatment.

Medical Conditions

Certain medical conditions can also contribute to shoulder pain upon waking up. Gallbladder disease, heart disease, liver disease, and lung disease are examples of conditions that can cause referred pain to the shoulder. Referred pain occurs when pain is felt in an area that is not the source of the problem. If you have an underlying medical condition and are experiencing shoulder pain, it is important to consult with your healthcare provider for further evaluation.

In summary, there are various causes of shoulder pain upon waking up, ranging from muscle imbalances to medical conditions. Understanding the underlying cause of your shoulder pain can help guide appropriate treatment and management. If your shoulder pain persists or worsens, it is recommended to seek professional medical advice from a healthcare provider or a qualified healthcare professional.
