What should I do about aching arm muscles?

Arm muscle pain may be caused by overuse, muscle strain, or fatigue. The following are some suggestions for managing and relieving symptoms: 1. Ice and heat therapy: If the pain has just occurred, apply cold compresses within the first 24 hours to help reduce swelling and pain. After 48 hours, switch to heat therapy to promote blood circulation and speed up recovery. 2. Gentle stretching and mild exercise: Perform gentle muscle stretching and mild joint movement to help relieve stiffness, but avoid strenuous activity that might worsen the injury. 3. Massage and relaxation: Lightly massage the sore area or use tools such as foam rollers to help relax the muscles. 4. Maintain good posture: If the pain is caused by prolonged poor posture, adjust your work and lifestyle habits, and use supportive devices such as neck pillows or lumbar cushions for office chairs. If muscle pain persists, accompanied by swelling, numbness, color changes, or inability to use the arm normally, seek medical attention promptly.
