Why does my mother have diabetic neuropathy?
Nerves are living conduits of electrical impulses. Neuropathy means the nerves do not conduct the electrical signal well. The causes of neuropathy include metabolic diseases like diabetes. The treatment of the pain includes medications to decrease the abnormal firing of the impaired nerves like gabapentin. A low dose is better than a high dose because the side effects especially sedation are lower with a lower dose. READ MORE
