“Signals from your peripheral nerves – the nerves located outside of the brain and spinal cord – are responsible for a host of functions, from perceiving sensations to allowing movements and supporting balance. But sometimes these signals get disrupted for various reasons. The result is a condition known as peripheral neuropathy.
Peripheral neuropathy can be caused by health conditions such as diabetes, rheumatoid arthritis, lupus, kidney disease, Lyme disease, shingles, and hepatitis. Other conditions that can cause peripheral neuropathy include having poor blood flow to the legs (often caused by peripheral arterial disease, or PAD), an underactive thyroid gland (hypothyroidism), metabolism problems, nutritional deficiencies, and growths or tumors that press on nerves.”
