Numbness and Imbalance
The peripheral nerves translate sensory input from the environment into neural impulses. Therefore, damage to the peripheral nervous system may impair sensory perception and the transmission of sensory information to the brain. Loss of sensation in a bodily part, or numbness, is a frequent symptom of many neurological problems, primarily in peripheral neuropathy. Some sensations may be lost when nerves are damaged because they are no longer sent or relayed through the PNS. Depending on the severity, patients can have difficulties perceiving hot and cold substances and feeling the texture and quality of the materials around them.
On the other hand, damage to the nerves from the brain and spinal cord to the legs and feet leads to imbalance and clumsiness. It shows up as “numbness” or reduced feeling in certain spots on the foot. Peripheral neuropathy disrupts the body’s ability to sense its position in space. Pain and other sensations are sent via nerves and used by the brain to pinpoint the position of the limbs. Although they are essential for maintaining equilibrium and agility, these feelings often go under the radar of the conscious mind. In addition, numbness in neuropathy is accompanied by muscle atrophy and weakness.
