Diagnosing the underlying cause of cold extremities involves a combination of medical history, physical examination, and diagnostic tests. These may include:
Blood Tests: To check for anemia, thyroid function, and blood sugar levels. Doppler Ultrasound: To assess blood flow in the arteries and veins. Nerve Conduction Studies: To evaluate the function of peripheral nerves. Thermography: To measure the heat distribution in the extremities.
