In the past 6 months, the pain has become much worse and disturbs his sleep. He has a history of type 2 diabetes mellitus and essential hypertension. Which of the following best represent the etiology of this patients condition?? A: Autonomic neuropathy, B: Isolated cranial nerve neuropathy, C: Isolated peripheral nerve neuropathy, D: Distal symmetric sensorimotor polyneuropathy, E: Radiculopathy,  <response>: This patient has a history of type 2 diabetes mellitus and is experiencing burning and shooting pains in his feet and lower legs that are worse at night and have progressed over the past 6 months. This presentation is most consistent with distal symmetric sensorimotor polyneuropathy, a type of diabetic neuropathy that affects the distal extremities in a length-dependent pattern. Autonomic neuropathy, cranial nerve neuropathy, and radiculopathy would not explain the symmetric distal distribution. Isolated peripheral neuropathy would not be expected in the setting of longstanding diabetes.D: Distal symmetric sensorimotor polyneuropathy
