What causes numbness in the hands and feet? These three are the most common

In life, when people's bodies show numbness, they can understand the relevant causes based on the different parts of the body where the numbness occurs. So, what causes numbness in hands and feet?

Cervical Spondylosis

Due to cervical vertebrae hypertrophy or cervical disc degeneration and protrusion compressing the cervical nerve roots or cervical spinal cord, numbness and pain in unilateral or bilateral fingers can occur, and gradually develop to the upper arm and forearm, and even cause upper limb movement disorders.

Common cervical spondylosis will cause headaches, dizziness, numbness and pain in the limbs. Don't worry, it can be relieved by taking active and effective methods. The effect of Western medicine in treating such diseases is not very ideal. In addition to oral medications, the only option is surgery. And generally cervical surgery is not recommended because the neck is densely populated with nerves. There are great risks, and massage and traction cannot relieve the pain.

Neuritis

Peripheral neuropathy most commonly affects the femoral nerve, sciatic nerve, median nerve, radial nerve, ulnar nerve, sural nerve and lateral femoral cutaneous nerve. Early symptoms are mainly sensory disturbances, but electrophysiological examinations often show that both motor and sensory nerves are affected. Clinically, the symptoms are symmetrical pain and paresthesia, with symptoms in the lower limbs being more common than in the upper limbs. Abnormal sensations include numbness, crawling ants, fever, and electric shock-like sensations, which often spread from the distal toes to above the knees. Patients feel like they are wearing socks and gloves. In cases with severe sensory impairment, lower limb arthritis and ulcers may occur. The pain is stabbing, burning, and drilling, as if it is hurting deep in the bone marrow. Sometimes there is a sense of tactile allergy, and even the inability to bear the pressure of the quilt, so the quilt must be propped up. When the motor nerves are affected, muscle strength often decreases to varying degrees, and in the late stage there is nutritional muscular atrophy. Peripheral neuropathy can be bilateral, unilateral, symmetrical or asymmetrical, but bilateral symmetry is more common.

Lumbar spondylosis

Lumbar spondylosis only causes numbness in the lower limbs, and no numbness in the upper limbs occurs. This is mainly caused by compression and other stimulation of the nerves in the corresponding segments of the lesion. The nerve roots in the lumbar spinal canal and their course are mainly distributed in the pelvic cavity and lower limbs, while the nerves and their nerve roots running in the upper limbs are mainly located in the cervical spinal canal. Therefore, if a patient with lumbar spondylosis also experiences numbness in the hands and feet, it should be considered that he or she may have cervical spondylosis. The main reason for numbness in the hands and feet is degenerative changes in the cervical and lumbar spine. Degenerative changes in the cervical and lumbar vertebrae can lead to herniated discs or hyperplasia and hypertrophy of the articular processes in the cervical and lumbar vertebrae. This may compress the nerve roots running through the upper and lower limbs in the spinal canal, or cause numbness in the hands and feet due to compression and stimulation of the nerve roots in the intervertebral foramen by bone hyperplasia of the uncovertebral joint.
