The feet and legs are more likely to be affected before hands and arms. According to the National Diabetes Information Clearinghouse, symptoms of peripheral neuropathy may include: * Numbness or insensitivity to pain or temperature * Tingling, burning or prickling sensation * Sharp pains or cramps * Loss of balance and coordination Nick has some of the symptoms that have been listed. There could be some damage to the central nervous system but not very severe or the symptoms that Nick exhibits would be more severe. C. Diabetic neuropathies damage peripheral nerves. Which component of the reflex arc is most likely to be damaged in Nick’s situation?
