As discussed, PAD limits blood flow to the legs. This is why one may experience changes in the colour of the legs and feet.
If left untreated, your legs can start turning pale or blue and you may experience a painful ache in your leg, especially when you’re walking. This pain may subside with a few minutes of resting.
According to the Mayo Clinic, coldness, numbness and weakness in the lower leg or foot, especially when compared with the other side, can also be a tell-tale sign of high cholesterol.
