Causes of arm pain

1. Frozen shoulder

Scapulohumeral periarthritis, in short, is the abbreviation for inflammation around the shoulder joint. Frozen shoulder is the main cause of pain when inflammation occurs around the shoulder joint.

The frozen shoulder we usually refer to mainly refers to people around 50 years old, who have "frozen" shoulder joints for no obvious reason, mainly characterized by shoulder movement dysfunction and soreness.

The onset of frozen shoulder is relatively slow. The pain usually starts without you noticing and gradually gets worse. For a disease like frozen shoulder, early detection and early treatment are essential. This will relieve the pain caused by frozen shoulder.

2. Lung cancer

Sometimes you will feel shoulder pain after a day's work. Many people think that this is a common phenomenon and it is not an exaggeration. However, no one would have thought that shoulder pain may be caused by lung cancer.

Typical symptoms of lung cancer include persistent cough, blood in sputum, difficulty breathing, chest pain, etc.

However, a small number of patients have special manifestations. For example, they do not have respiratory symptoms such as coughing and hemoptysis, but instead have symptoms such as shoulder pain, neck swelling, upper abdominal pain, loss of appetite, and headache.

This is because the apex of the lung is right above the chest outlet, and there are many nerve plexuses in the surrounding area, such as the brachial plexus. When cancer occurs at the apex of the lung.

As the tumor continues to grow, it may compress or invade the pleura at the apex of the lung and surrounding areas, causing symptoms similar to frozen shoulder, such as pain in the shoulder joint and shoulder and back muscles.

3. Cholecystitis

Since the gallbladder is located on the right side of the human body, the pain of gallstones or cholecystitis usually radiates to the right shoulder or right shoulder blade, and patients often have a history of recurrent attacks.

In severe cases, the pain is unbearable, the patient may be restless, bend over with his hands on his stomach, fall to the ground and writhe, scream and shout, have a pale face, sweat profusely, or may be accompanied by nausea, vomiting, and even shock.

4. Angina

The pain caused by myocardial infarction and cholecystitis is in the opposite location. The pain caused by myocardial ischemia radiates to the left shoulder.

5. Cervical spondylosis

Cervical spondylosis is caused by long-term incorrect work and living posture. The cervical vertebra is prone to degenerative diseases such as hyperplasia, which compresses the nerves and causes shoulder pain. This type of pain accounts for a relatively large proportion.
