Cold feet are not always vascular
Cold feet can be related to temperature, nerve problems, thyroid issues, anemia, medications, or reduced blood flow. Vascular assessment becomes more important when coldness is one-sided, painful, associated with color change, weak pulses, wounds, diabetes, or walking pain.
Tests that may be useful
ABI, Doppler waveform assessment, and arterial duplex ultrasound help evaluate whether blood flow to the legs and feet is reduced and where narrowing may be located.
