If the symptoms of cold joints occur, the first thing to consider is whether there is a problem with blood circulation to the joints. Once blood circulation is impaired in the soft tissues around the joints or inside the joints, the soft tissues around the joints and the tissues inside the joints will become ischemic and hypoxic, thus causing the symptoms of cold joints. Secondly, cold joints can also be caused by the lack of liver and kidney energy and the deterioration of the body’s functions, mostly in the middle-aged and elderly. In addition to cold joints, other symptoms such as back and leg pain, soreness and weakness of the lower back and knees may also occur. Finally, there may be abnormal sensations that occur after nerve compression or stimulation. For example, compression of the human sciatic nerve or compression of the lumbar or sacral nerves can cause symptoms of coldness, chills, or even numbness and pain in the entire sciatic nerve distribution area. Therefore, if you have symptoms of cold joints, you should ask a professional orthopedic surgeon for an early examination and timely treatment.
