What causes pain inside the bones of the arm?

Generally, the main causes of pain inside the arm bone include overexertion, arm exposure to cold, lateral epicondylitis, periarthritis of the shoulder, and periostitis. If discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. Specific analysis is as follows:

1. Overexertion

Long-term heavy lifting or frequent arm swinging can repeatedly strain the arm muscles, pulling on the bones and stimulating the periosteum, leading to pain. Symptoms often improve with rest. Reduce activities involving arm load-bearing; elevate the arm during rest; gently massage the arm muscles; and avoid sudden increases in arm exercise intensity in daily life.

2. Arm Exposure to Cold

Cold invasion causes blood vessels around the arm bones to constrict, slowing circulation and reducing local blood supply, which may trigger pain that worsens in cold conditions. Promptly wear warm clothing, apply a hot water bottle to the affected arm, avoid prolonged exposure to cold environments, and perform gentle arm movements to promote blood flow.

3. Lateral Epicondylitis (Tennis Elbow)

Repetitive arm motions over time cause cumulative tendon damage at the lateral epicondyle of the humerus, resulting in an aseptic inflammation. This inflammation irritates the underlying bone, causing deep bone pain in the arm, which worsens when twisting a towel or lifting objects. Under medical guidance, medications such as ibuprofen sustained-release capsules, diclofenac sodium enteric-coated tablets, or etoricoxib tablets may be used. Wearing an elbow brace can provide protection, and in severe cases, surgical release of the lateral epicondyle may be required.

4. Periarthritis of the Shoulder (Frozen Shoulder)

Adhesions in the soft tissues surrounding the shoulder joint allow inflammation to spread to the humerus, causing deep bone pain in the arm, accompanied by restricted shoulder movement and difficulty raising the arm. Under medical supervision, medications such as celecoxib capsules, eperisone hydrochloride tablets, or Huoxue Zhitong capsules may be prescribed. Stretching exercises for the shoulder joint are beneficial, and in severe cases, arthroscopic shoulder release surgery may be necessary.

5. Periostitis

Trauma or excessive exercise can lead to congestion and edema of the humeral periosteum, triggering inflammation. This inflammatory process stimulates the bone nerves, causing deep arm bone pain along with localized swelling. Under medical guidance, medications such as naproxen sodium tablets, acetaminophen tablets, or indomethacin enteric-coated tablets may be taken. Limit arm activity, and in severe cases, surgical periosteal decompression may be required.

In daily life, avoid long-term heavy lifting and repetitive arm movements; keep the arms warm to prevent cold exposure; warm up thoroughly before exercising to prevent overuse; strengthen arm muscle training to enhance skeletal stability; and seek prompt medical attention for persistent pain to identify the underlying cause and receive appropriate treatment.
