The general common causes of tingling sensation in the hands and feet are exertion and improper posture. Cervical spondylosis, herniated disc, cerebrovascular disease and other nerve compression or injury can also be caused.
Exhaustion or long time to maintain a fixed posture easily lead to muscle swelling, swelling muscle compression of blood vessels or nerves, resulting in poor blood supply to the local nerves. The nerve response is slow and numbness in the hands and feet may occur. After the compression is lifted, blood circulation can be restored and the numbness will subside and disappear.
Cervical disc herniation can compress the nerves of the upper limbs, causing numbness of the hands; lumbar disc herniation can compress the nerves of the lower limbs, causing numbness of the legs and feet.
Cerebrovascular diseases, including cerebral infarction, cerebral hemorrhage, etc., can cause numbness in the limbs of half of the body due to the damage of local nerves in the skull.
Peripheral neuritis can also cause peripheral nerve damage, resulting in numbness in the hands and feet.
If you feel numbness in your hands and feet and it is not relieved after resting for a long time, you need to go to the hospital for examination and diagnosis, so as to clarify the cause of the disease and then treat it.
