Peripheral artery disease (PAD) is a common circulatory problem that is the result of reduced blood flow to the legs. Common PAD symptoms include painful cramping in the hip, thigh, and calf muscles; numbness or weakness in the legs; coldness in the lower legs or feet; a change in leg color; hair loss or slow hair growth on the lower legs; slower toenail growth; shiny skin on the legs; and weak pulsing sensation in the legs. If you are suffering from some of these symptoms, talk with your healthcare provider. Mayo Clinic, September 2021
