Weakness in the shoulders: causes, symptoms, and treatment
About the Symptom
Weakness in the shoulders is a common symptom that can affect people of all ages and professions. It may manifest as a general feeling of fatigue and lack of strength in the shoulder area, as well as more pronounced sensations, such as difficulty in raising the arms or performing daily tasks. Often, shoulder weakness is accompanied by painful sensations, burning, or numbness, which may intensify with physical activities or certain movements. Understanding the causes and diagnosing this symptom are crucial for determining an effective treatment course.
The causes of shoulder weakness can be varied: from simple muscle overexertion to more serious conditions, such as neuropathies associated with nerve damage or joint pathologies. In athletes, shoulder weakness may arise from repetitive injuries or overloads, while office workers may experience it from prolonged static postures. Stress and emotional state often play a role as well, which can also affect muscle tone and strength. It is important not to ignore this symptom and to consult specialists for comprehensive diagnosis and the selection of adequate treatment methods.
Diseases
Weakness in the shoulders may be a symptom of various diseases that can affect both the nervous and muscular systems. Most often, patients encounter conditions such as osteochondrosis, myositis, and neuritis. Cervical osteochondrosis not only causes severe pain but may also lead to weakness and numbness in the shoulder area, as nerve compression hinders nerve transmission. Myositis, which is inflammation of the muscles, can arise due to infections or intense strain and lead to muscle strength weakening in the shoulders.
Additionally, diseases of the peripheral nervous system, such as carpal tunnel syndrome, can also cause weakness in the shoulders if they affect the area of innervation of the upper limbs. It is important to note that weakness in the shoulders may be a consequence of more serious diseases, such as infectious processes, rheumatic diseases, or even tumors. Therefore, if this symptom appears, it is recommended to consult a doctor for a complete diagnosis and qualified medical assistance.
- Cervical osteochondrosis
- Myositis
- Neuritis of the brachial nerve
- Carpal tunnel syndrome
- Rheumatoid arthritis
- Tendovaginitis
- Infectious diseases (e.g., viral infections)
- Neoplasms
Diagnosis
To determine the causes of weakness in the shoulders, a comprehensive diagnosis is necessary, which includes both a clinical examination and laboratory and instrumental studies. A neurologist, starting with an in-depth history taking, will assess the nature of the pain, its intensity, and accompanying symptoms. This will help identify possible risk factors and determine the correct direction for diagnosis.
Questions about the patient’s habits, previously sustained injuries or illnesses, as well as the nature of physical activity are of significant importance for identifying the source of weakness. Furthermore, performing additional diagnostic procedures will allow for a more accurate determination of whether the patient’s condition is related to muscular, neural, or joint problems.
- Complete blood count and biochemical blood analysis
- Electromyography (EMG)
- Magnetic resonance imaging (MRI) of the cervical and thoracic spine
- Computed tomography (CT)
- Ultrasound examination (US) of the shoulder joint
- X-ray
- Testing for functional impairments (e.g., strength tests and movements in the shoulders)
Which Doctor to Contact
Weakness in the shoulders can be a sign of various medical conditions, so it is important to correctly determine which specialist will help you with this problem.

Types of Shoulder Weakness
Shoulder weakness can manifest in various forms and may be associated with a multitude of causes. The main types of weakness may include general muscle weakness, which often occurs as a result of physical overexertion, lack of physical activity, or metabolic disorders. In this case, there is difficulty in performing routine daily tasks, such as lifting objects or keeping the arms raised.
Another type is local weakness, which may be related to injuries or diseases of specific muscles or joints in the shoulder girdle. In this case, the patient may experience pain and limited movement, as well as a noticeable reduction in muscle strength on one side of the body. This type of weakness can also be a consequence of neurological disorders that affect the transmission of nerve signals to the muscles.
- General muscle weakness
- Local weakness of the shoulder muscles
- Weakness related to neurological disorders
- Weakness due to joint injuries or diseases
- Functional weakness from overexertion or lack of physical activity
Causes of Weakness in the Shoulders
Weakness in the shoulders can occur for various reasons, and each of them requires special attention. One of the main causes is injury. Bruises, strains, and even fractures can lead to reduced strength and coordination, resulting in discomfort and difficulty in movement for the patient. Damage to ligaments and tendons, such as the rotator cuff, can also be a cause of weakness in the shoulders.
In addition, weakness in the shoulders may be a consequence of diseases such as osteoarthritis or rheumatoid arthritis, which impair the functionality of the joints. Neuropathies, such as carpal tunnel syndrome, can affect the nerves responsible for sensitivity and strength in the shoulders, causing paralysis or weakness. Lifestyle factors, such as sedentary behavior, excessive physical strain, or poor posture, are also significant and can provoke the appearance of this symptom.
- Shoulder joint injuries
- Osteoarthritis
- Rheumatoid arthritis
- Neuropathies
- Muscle strain
- Spinal problems
Common Associated Pathologies
Weakness in the shoulders may not be an isolated symptom, but rather a manifestation of various pathologies affecting the muscles, nerves, or joints in this area. One of the most common associated pathologies is shoulder girdle syndrome, which occurs due to compression of the nerves running through the brachial plexus. This can lead to pain, numbness, and weakness, making it difficult to perform daily tasks.
Another common cause of shoulder weakness is pathologies related to the shoulder joint, such as osteoarthritis or gout. These conditions can cause inflammation and pain, resulting in difficulties with movement and weakness in the shoulder muscles. The presence of injuries, such as dislocations or strains, can also lead to similar symptoms, worsening the overall functionality of the shoulder joint.
- Shoulder girdle syndrome
- Osteoarthritis of the shoulder joint
- Gout
- Strains and ligament injuries
- Brachial plexus neuropathy
- Tendon sheath inflammation
- Shoulder bursitis
Expert Opinion
Weakness in the shoulders is a symptom that may indicate a range of conditions, both functional and pathological. It is important to understand that this sign often does not occur in isolation and is accompanied by other symptoms such as pain, numbness, or limited mobility. Consulting with a neurologist or orthopedic specialist can help establish an accurate diagnosis and select an appropriate treatment strategy.
Scientific studies show that many patients experiencing weakness in the shoulders may suffer from shoulder joint or nervous system disorders. In cases where shoulder weakness is caused by advanced diseases such as brachial neuropathy or osteoarthritis, treatment may require a more comprehensive approach, including physical therapy, medication, and, in some cases, surgical intervention. Therefore, it is essential not to postpone a visit to a specialist to avoid complications.
Experts strongly recommend against self-diagnosis and attempting to treat shoulder weakness independently, as this may not only exacerbate the problem but also delay the time to receive necessary medical care.
