If the patient develops leg numbness when meditating, it is mainly due to the sitting position, which leads to long-term local compression of the thighs, causing compression of blood vessels and nerves. When the vascular nerve is compressed, it will cause poor vascular reflux, including relatively poor blood supply to the distal region. At the same time, nerve compression can also cause some damage to the nerves, resulting in peripheral numbness and discomfort. Clinical relief, first of all, is to release the compression, improve the posture, the patient to take a standing position or standing walking, local massage can play a role in relief, the problem is not big. However, it should be noted that once the lower extremity numbness occurs, do not maintain a posture for a long time. Because the vascular nerve compression for too long, it can cause related diseases. For example, nerve damage or poor venous return, resulting in deep vein thrombosis in the lower extremities, which are more dangerous diseases, there are certain symptoms to improve the posture and adjust in a timely manner.
