Why does diabetes cause extreme sensitivity in the foot and the big toe is always numb?

Hi,When diabetes is poorly controlled over a long period of time, sometimes the sugar in your blood can damage the nerves in your feet. This causes loss of sensation (numbness) and pain (neuropathy). This is why you have been prescribed Lyrica (pregabalin).The best way to prevent the problem from getting worse is to keep your diabetes well controlled.Good evening,Alexandre Chagnon, pharmacist
