Which symptom best indicates diabetic distal symmetric neuropathy in a patient seeking physical therapy?

• A. Painful swelling in the knees.
• B. Blurred vision in both eyes.
• C. Distal symmetric numbness/tingling in the feet.
• D. Chest pain with exertion.

Answer: (C)

Diabetic distal symmetric neuropathy presents with sensory changes that start in the feet and legs and occur in a symmetric, distal pattern—the classic stocking-glove distribution. Numbness and tingling in the feet reflect nerve fiber damage from long-standing hyperglycemia and are the hallmark signs clinicians look for when screening a diabetic patient for neuropathy. This sensory loss helps explain why patients may have balance issues and a higher risk of foot ulcers due to loss of protective sensation, which is especially important for physical therapy planning and foot care education. The other symptoms aren’t neuropathy: painful swelling of the knees points to joint or inflammatory issues, blurred vision indicates retinopathy, and chest pain with exertion suggests cardiovascular problems.
