Why does the right arm hurt and feel strained when taking off a shirt?

Generally, the main causes of pain and difficulty in the right arm when taking off a shirt include temporary muscle strain, improper posture causing pulling, rotator cuff injury, biceps tendinitis, and shoulder periarthritis. If discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. Detailed analysis is as follows:

1. Temporary Muscle Strain

Repeatedly using the right arm to lift heavy objects or perform household chores recently can lead to muscle fatigue. Pain and effort may occur when raising the arm during undressing. Reduce load-bearing activities with the right arm, avoid overexertion, and apply appropriate massage to the arm muscles during rest. Use a warm towel to apply heat to the painful area for 15 minutes each time to relieve muscle fatigue.

2. Improper Posture Causing Pulling Injury

Moving too quickly or twisting the body while removing clothing may excessively stretch the muscles and ligaments of the right arm, resulting in transient pain and discomfort. Adjust your undressing posture, slow down movements, gently raise the right arm before removing clothes, and avoid sudden pulling. In daily life, maintain moderate range of motion for the arm.

3. Rotator Cuff Injury

Damage to the rotator cuff tissues in the right shoulder joint requires these structures to engage when lifting the arm during undressing, which stimulates the injured area and causes pain and discomfort. Under medical guidance, medications such as celecoxib capsules, diclofenac sodium sustained-release tablets, or glucosamine hydrochloride capsules may be used. In severe cases, arthroscopic rotator cuff repair surgery may be required. After surgery, avoid lifting heavy objects too early.

4. Biceps Tendinitis

Chronic wear and inflammation of the biceps tendon in the right arm leads to increased inflammatory irritation and pain when the tendon is stretched during undressing. Under medical supervision, take medications such as ibuprofen sustained-release capsules, loxoprofen sodium tablets, or naproxen sodium tablets. Combine medication with local immobilization and rest, avoiding excessive arm movement.

5. Shoulder Periarthritis (Frozen Shoulder)

Inflammation and adhesion of tissues surrounding the right shoulder joint restrict arm movement during undressing, and stretching of adhered tissues causes pain and effort. Under medical guidance, medications such as etoricoxib tablets, methylprednisolone tablets, or chondroitin sulfate sodium tablets may be taken. When necessary, shoulder joint release surgery may be performed, followed by gradual rehabilitation exercises after surgery.

In daily life, keep the right arm warm and avoid exposure to cold; slow down movements when undressing and maintain proper posture; avoid overusing the right arm to prevent muscle strain; perform appropriate shoulder joint stretching exercises regularly to maintain joint mobility; rest promptly when pain occurs to prevent worsening of injury.
