Neuropathy

The numerous potential causes for peripheral neuropathy . . .  Can cause damage to individual or multiple peripheral nerves, and once these nerves are injured, common symptoms may include weakness, numbness, and pain in the area where the nerves were damaged (https://www.mayoclinic.org/diseases-conditions/peripheral-neuropathy/symptoms-causes/syc-20352061). These injuries are known clinically as mononeuropathy (one peripheral nerve affected), multiple monneuropathy (two or more nerves in different areas affected), or polyneuropathy (multiple nerves affected) (https://www.mayoclinic.org/diseases-conditions/peripheral-neuropathy/symptoms-causes/syc-20352061).


Each peripheral nerve in the human body has a specific function; therefore, the symptoms of peripheral neuropathy can vary greatly depending on which nerves are affected. Peripheral nerves are classified into three categories: sensory nerves (which receive sensations such as touch, vibration, temperature, and pain from the skin), motor nerves (which control muscle movement), and autonomic nerves (which control functions such as blood pressure, heart rate, digestion, and bladder control) (https://www.mayoclinic.org/diseases-conditions/peripheral-neuropathy/symptoms-causes/syc-20352061).


Depending which of the aforementioned nerves are affected in a specific neuropathy case, the symptoms may include any of the following: gradual onset of numbness, prickling or tingling in your feet or hands (which can spread upward into your legs and arms), sharp, jabbing, throbbing, freezing or burning pain, extreme sensitivity to touch, lack of coordination and falling, muscle weakness or paralysis (if motor nerves are affected), heat intolerance and altered sweating (if autonomic nerves are affected), bowel, bladder or digestive problems (if autonomic nerves are affected), and/or changes in blood pressure (causing dizziness or lightheadedness; only occurs if autonomic nerves are affected) (https://www.mayoclinic.org/diseases-conditions/peripheral-neuropathy/symptoms-causes/syc-20352061).
