Neuropathy in the feet can lead to additional medical problems. A person with peripheral neuropathy may step on sharp objects or walk around with a stone in their shoe without noticing because the nerves in the feet aren't sending pain signals. Numbness also makes it hard to feel friction from socks or shoes that may cause blisters.
Because they go unnoticed, cuts and blisters aren't protected or treated, so small wounds can grow and infection may set in.
