What causes pain on the inner side of the arm?

In general, pain on the inner side of the arm may be caused by overuse, poor posture, cervical spondylosis, periarthritis of the shoulder, medial epicondylitis, and other factors. It is recommended to seek medical attention promptly and identify the underlying cause under the guidance of a professional physician before initiating treatment. Specific analyses are as follows:

1. Overuse

When the muscles, tendons, or ligaments in the arm are overused or suddenly stretched, minor tears or inflammation may occur, leading to pain on the inner side of the arm. It is recommended to get adequate rest and avoid excessive strain, which can help relieve the pain.

2. Poor Posture

Maintaining the same posture for prolonged periods may increase pressure on the muscles and nerves on the inner side of the arm, causing muscle tension and resulting in pain. Adjusting work and living environments appropriately, regularly changing postures, and performing stretching exercises can help alleviate discomfort.

3. Cervical Spondylosis

Cervical spondylosis may result from long-term cervical strain, bone spurs, and other factors, which can compress nerve roots and obstruct nerve conduction, thereby causing pain on the inner side of the arm. Patients often experience accompanying symptoms such as neck stiffness, headaches, and arm pain. Treatment may include medications such as meloxicam capsules, diclofenac sodium sustained-release capsules, and vitamin B1 tablets, as directed by a physician.

4. Periarthritis of the Shoulder

Periarthritis of the shoulder may be related to degeneration of soft tissues, trauma, or overuse. Inflammation of the soft tissues surrounding the shoulder joint causes shoulder pain, which may radiate to the inner side of the arm, resulting in pain in that area. Common symptoms include shoulder pain, restricted movement, and pain on the inner side of the arm. Medications such as ibuprofen sustained-release tablets, acetaminophen tablets, and methylprednisolone tablets may be used under medical supervision.

5. Medial Epicondylitis

Medial epicondylitis is usually caused by repeated pulling at the origin of the forearm flexor muscles, leading to inflammation and pain at the medial epicondyle of the humerus, thus causing pain on the inner side of the arm. Symptoms may include pain on the inner side of the elbow, increased pain during forearm exertion, and pain on the inner side of the arm. Medications such as celecoxib capsules, loxoprofen sodium tablets, and nimesulide tablets may be used as prescribed by a doctor.

It is recommended to avoid working with poor posture for extended periods, prevent excessive fatigue, ensure sufficient rest, and maintain regular daily routines to promote overall health.
