Pain in the shoulder joint is a very common complaint. From such trouble nobody is insured, as this is one of the most mobile joints in the human body. Such a physiological feature is also a virtue( it provides a greater amplitude of movements of the upper limb), and a disadvantage( the shoulder joint due to the characteristics of its anatomical structure is very susceptible to various negative factors).
What if the shoulder joint hurts? The answer to this question is one: to determine the cause of the painful sensations and to begin treatment.
Features of the structure of the shoulder joint
First of all, it should be noted that the joint of the shoulder belongs to the spherical joint. This allows you to perform movements in all directions( flexion and extension, withdrawal and reduction, pronation and supination).In the body there is no more articulation with such a wide range of movements. All this allows the person to perform any movements with his hands, but at the same time leads to a shoulder vulnerability.
The shoulder joint consists of the articular cavity of the scapula and the head of the humerus, which is several times larger than the depression in the area. This particular feature contributes to frequent dislocations and subluxations in the shoulder.
But nature took care of man and created a stabilizing apparatus of this joint, which consists of:
- cartilage tissue that is located at the edges of the articular cavity of the scapula and increases the area of contact with the head of the shoulder;
- of the articular capsule, which captures large enough bones;
- numerous intraarticular and extraarticular ligaments, which stabilize their joints with their fibers and compact the capsule;
- powerful muscular framework;
- processes of scapula and tendon muscles, which form a kind of roof over the joint.
Despite all these stabilizing elements, the shoulder is very prone to injury and various diseases. And given its complex structure( many synovial bags and other anatomical formations), it is almost impossible to determine why the shoulder joint hurts without additional diagnostic methods( X-ray, MRI, ultrasound).
As can be seen, the area of contiguity of the head of the humerus and articular cavity of the scapula is very small, which provides the vulnerability of the shoulder joint
. The main causes of
All causes of pain in the shoulder joint can be divided into 3 groups:
- Associated with damage to the structures of the joint itself.
- Conditioned by the pathology of the periarticular tissues( muscles, tendons, synovial bags, scapula processes, vessels and nerves).
- Those that arise from the defeat of internal organs.
The pathology of the joint
First of all, if the shoulder joint is badly hurting, it is necessary to exclude its traumatic damage. A fall on the straight arm, a blow to the shoulder area, a sharp movement of the upper limb, a prolonged load on the shoulder joint and other factors can cause pathological symptoms. Pain can cause as a simple bruise, and a dislocation, subluxation, intraarticular fracture of the humerus, sprain or ligament rupture.
Falling on an elongated arm is the most common cause of shoulder dislocation and acute pain
. The pain occurs immediately after the impact of the traumatic factor, increases during active and passive movements, which makes them impossible. Indications for trauma plus characteristic symptoms give the doctor the opportunity to suspect pathology, and the radiograph and ultrasound of the shoulder will help to clarify her character. To treat you in this case will be a traumatologist, it is not impossible to impose a cast or surgical fixation for fractures.
Often the cause of pain is arthrosis of the shoulder. It is a degenerative-dystrophic disease that affects mainly older people, but it also occurs in certain groups of young people( those who have predisposing factors of lesions of intraarticular cartilage of the shoulder joint).If you are an athlete and you crunches and hurts after training your shoulder, you must suspect arthrosis and seek medical help.
Also the cause of pain in the shoulder can be such diseases as tendonitis( inflammation of the tendons and ligaments of the shoulder), bursitis( inflammation of the joint capsule) of various genesis( infectious and aseptic).
A large group of lesions of the shoulder joint is rheumatological diseases. Most often the shoulder is affected by rheumatoid arthritis and Bekhterev's disease, but the shoulder joint can be retracted into the pathological process in any connective tissue diseases with the development of arthritis.
Very rarely, as a cause of pain in the shoulder, tumor lesions and congenital anomalies of the joint structure may occur.

Gymnastics for arthrosis of the shoulder joint
First place in the prevalence in this group of reasons for shoulder pain is the humeropathy periarthritis. It is an inflammation of the periarticular tissues( tendons) and the surface layer of the joint capsule. The main symptoms that help to recognize the pathology are: the joint is very sore for no apparent reason, painful sensations appear mainly at night, as the disease progresses, the pain becomes permanent and strong, which causes the person to apply all the methods of treatment known to him. Soreness increases when trying to actively move, especially when leaning over the shoulder, lifting the arm up, putting it behind the head. The disease lasts for a long time( up to several months), without adequate treatment leads to the development of stiffness in the joint and a decrease in the amplitude of movements.
The second place is occupied by the pathology of the cervicothoracic spine. Osteochondrosis of this part of the spinal column with the development of radicular syndrome is often the cause of shoulder pain, which is often confused with arthrosis. To suspect a pathology it is possible on communication or connection of amplification or occurrence of a pain after turns by a head and a trunk, other signs, for example, a numbness of arms or hand. To treat such a disease is necessary in a complex way - medicines, exercise therapy, massage, manual therapy, stretching, etc.
Sometimes the cause of pain can become a "collision syndrome".This calcification( deposition of calcium salts) tendons and subacromial synovial bags, which are between the acromial process of the scapula and the shoulder joint. Pain occurs during movement, is intense and sudden in nature, resembles a gout attack. People often suffer from the age of 40 years.
Collision syndrome often causes pain in the older age group
Plexitis( inflammation) of the brachial plexus can also cause joint pain.
Internal diseases that occur with pain in the shoulder
In some cases, pain in the shoulder joint is reflected. In acute or exacerbation of chronic cholecystitis( inflammation of the gallbladder), cholelithiasis, pain can be localized not in the right upper quadrant, but in the right shoulder.
Pain in the left shoulder can indicate a heart attack. They can occur as equivalents of chest pain with angina pectoris or be the only symptom of myocardial infarction.
Also, soreness in the shoulder sometimes occurs with pneumonia, pleurisy, tumors of the pulmonary-bronchial apparatus.
In each case, if you are worried about shoulder pain without objective reasons, you need to seek medical help. Only a thorough medical examination using additional diagnostic techniques will help to establish the correct diagnosis and choose an adequate and effective treatment.
