The causes of numbness and pain in the hands and feet are mainly twofold: 1. Excessive strain on the muscles and soft tissues of the hands and feet, as well as the formation of inflammatory edema and bruising, can easily lead to pain. In addition, local swelling may lead to an increase in local tension, which may stimulate the peripheral nerves and lead to numbness. 2, abnormalities in the nerve tissue, such as cervical spondylosis, may lead to stimulation of the nerve fibers in the spinal cord, resulting in a decrease in nerve function, and may lead to numbness and pain in the hands and feet. It is also possible that neurogenic cervical spondylosis combined with lumbar disc herniation may also lead to nerve root stimulation, resulting in nerve tissue stimulation in the hands and feet and related numbness and pain. Therefore, it is best to go to the orthopedic department of a hospital after this condition for a medical examination to clarify the condition and carry out targeted treatment.
