Muscle pain in the limbs may be related to overwork, osteoporosis and severe cervical spondylosis. If you do intense physical labor and long-distance running, mountain climbing and other intense sports, the symptoms of limb muscle soreness will occur during rest, which is caused by the accumulation of lactic acid in the muscles due to a large amount of anaerobic fermentation, and can be relieved naturally by resting for a few days. Middle-aged and elderly people, especially postmenopausal women, if there is no obvious reason for limb pain, may be related to osteoporosis. A large loss of calcium in the body can lead to limb pain and muscle weakness. In severe cervical spondylosis, spinal cord nerve compression can also cause limb pain, numbness, muscle atrophy, and walking weakness. Cold and fever will increase the body’s oxygen consumption, muscle anaerobic fermentation to produce lactic acid, will also cause limb muscle soreness. If the symptoms of muscle pain in the limbs occur, it is recommended that the patient go to the hospital for medical examination to clarify the cause of the disease and then treat the cause.
