Peripheral neuropathy refers to the many conditions that involve damage to the peripheral nervous system, the vast network of nerves that sends signals between the central nervous system (the brain and spinal cord) and all other parts of the body.
Over time our nerves experience a loss of blood supply from constriction which leads to degeneration. A damaged nerve will start to send abnormal signals to the brain which will bring sensations of burning, tingling, and intense pain that you might be experiencing.
Further, more serious progressions of nerve damage will present themselves as numbness. If the sensation loss is found in the feet, the serious risk of falling becomes more prevalent. Nerve damage in your hands could lead to a weaken grip and dropping things.
