Diabetic peripheral neuropathy is the most likely diagnosis for someone with diabetes who has pain in the upper and lower extremities. It may feel like pins and needles, throbbing or burning and frequently intensifies at night. It is the result of blood sugar levels being and staying high, when diabetes is not or poorly controlled. Sometimes, it may be the first symptom of diabetes.
A primary goal is to maintain sugar levels in a tight normal range in order to minimize further spikes that predispose to further nerve damage, which is unfortunately irreversible. But solutions exist to minimize discomfort and enable increased activities and better rest.
