Why does periarthritis of the shoulder hurt severely when exposed to cold?

Severe shoulder pain caused by exposure to cold in patients with shoulder periarthritis may result from physiological factors, or could be due to pathological conditions such as rotator cuff injury or degenerative joint disease. It is important to promptly identify the underlying cause and choose appropriate treatment under a doctor's guidance. A detailed analysis is as follows:

I. Physiological Factors

Long-term heavy use of the shoulder or prolonged residence in cold environments after onset of the condition can lead to shoulder muscle strain and exacerbate pain symptoms. It is recommended to get adequate rest, avoid excessive fatigue, and enhance personal warmth protection.

II. Pathological Factors

1. Rotator Cuff Injury

Injuries or repetitive movements may cause varying degrees of rotator cuff damage. Once exposed to cold, local blood circulation may be impaired, resulting in pain and restricted movement. During the acute phase, follow medical advice to take medications such as ibuprofen sustained-release capsules, loxoprofen sodium capsules, or diclofenac sodium sustained-release tablets, which inhibit prostaglandin secretion and provide pain relief.

2. Degenerative Joint Disease

Trauma to the shoulder joint may lead to joint instability. In severe cases, degeneration and damage of articular cartilage occur, causing symptoms such as joint pain, limited mobility, and deformity. Mild cases may be treated under medical supervision with sodium hyaluronate injection, chondroitin sulfate tablets, or meloxicam tablets. Severe cases may require surgical intervention such as articular cartilage repair. Adequate rest is essential after surgery.

Besides the above, conditions such as periarthritis, rheumatoid arthritis, or gouty arthritis may also be responsible. Patients experiencing these symptoms should cooperate closely with their doctors’ treatment plans, avoid overexertion, and maintain proper body warmth.
