Introduction
In general, whole-body muscle pain may be caused by excessive exercise, lack of sleep, influenza, rheumatoid arthritis, polymyositis, or other conditions. If discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. In daily life, exercise should be gradually increased to avoid overexertion, and regular sleep patterns should be maintained to prevent chronic sleep deprivation.
Generally, body-wide muscle pain may be caused by excessive exercise, lack of sleep, influenza, rheumatoid arthritis, polymyositis, or other reasons. If discomfort symptoms occur, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. Specific analysis is as follows:
1. Excessive exercise: When physical activity exceeds the body's capacity, anaerobic respiration in muscles leads to lactic acid buildup, which stimulates nerves and causes soreness. Stop intense activities, gently massage the muscles, take warm baths to promote lactic acid metabolism, and replenish protein and electrolytes.
2. Sleep deprivation: Chronic poor sleep disrupts the body's metabolism, preventing muscles from fully repairing, resulting in diffuse pain. Adjust your schedule to ensure 7–8 hours of sleep per night, avoid staying up late before bedtime, and create a quiet, comfortable sleeping environment.
3. Influenza: Influenza viruses invade the body and release toxins that stimulate muscle tissue, causing muscle aches accompanied by fever. Follow medical advice to use Oseltamivir Phosphate Capsules, Paracetamol Tablets, or Lianhua Qingwen Capsules. Rest adequately and drink plenty of water.
4. Rheumatoid arthritis: Abnormal immune responses attack joints and surrounding muscles, leading to chronic pain and stiffness. Follow medical advice to use Methotrexate Tablets, Celecoxib Capsules, or Sulfasalazine Enteric-coated Tablets, and avoid exposing joints to cold or damp conditions.
5. Polymyositis: Immune-mediated attacks on muscle fibers cause muscle inflammation and necrosis, resulting in symmetric muscle pain and weakness. Follow medical advice to use Prednisone Tablets, Methylprednisolone Tablets, or Azathioprine Tablets; in severe cases, plasma exchange may be required.
In daily life, exercise should progress gradually to avoid overexertion; maintain regular sleep habits and avoid chronic sleep deprivation; pay attention to staying warm and preventing infections; undergo regular health check-ups, and promptly investigate the underlying causes if persistent muscle pain occurs.
