Pain/numbness, motor weakness caused by spinal nerves

What are the symptoms of damage to the nerves in the spinal cord?

Roughly speaking,

Cervical spine: Numbness and pain from shoulders to hands and fingers, difficulty in applying force to fingertips,

Lumbar spine: Pain / numbness from the waist to the legs, difficulty in applying force to the legs

In reality, the symptoms of nerve compression are different for each level of the bone in the cervical and lumbar spine.

The figure below shows the specific areas of pain / numbness and movements that are difficult to apply force, for each place where nerves are pressed.

I select and write nerves that are particularly susceptible to damage. The area surrounded by red is the place where you feel numbness or pain.

If you are suffering from similar pain, numbness, or weakness, the cause may be the nerves of the spinal cord.

If some of the below apply, we recommend you to visit the clinic.
