If a diabetic person suffers numbing, tingling pain in arms, hands, legs, and feet, he most likely is suffering from Peripheral Neuropathy. Recovery is slow. Sometimes, it progresses to muscular atrophy. Pain relief may come from a variety of drugs: Tricyclics (e.g. amitriptyline), Venlafaxine (Effexor-XR), Gabapentin (Neurontin), Pregabalin (Lyrica), Opioids (e.g. OxyContin).
