When to worry about cold hands and feet with peripheral arterial disease

Peripheral arterial disease narrows or stiffens arteries supplying the limbs. Reduced blood flow may make a foot or hand feel cooler and may occur with aching during walking, slow-healing wounds, shiny skin, reduced hair growth, or a change in colour. Symptoms can affect one or both sides. Temperature alone does not show how much blood flow is available, so changes deserve attention.

Check your hands and feet regularly for skin breaks, colour changes, swelling, or new tenderness. Protect them from cold and injury, wear well-fitting footwear, and avoid putting direct heat on areas with reduced sensation. Keep appointments for vascular review and use prescribed medicines as directed. Report a new walking limitation, rest pain, or wound promptly rather than waiting for the next routine visit.

Treat a suddenly cold, pale, blue, painful, numb, or weak limb as an emergency, especially if you cannot move it normally. Seek urgent care for a new wound that is not healing, spreading redness, blackened skin, or severe pain at rest. Chest pain, severe breathlessness, or collapse also requires emergency help.

Ask how your circulation will be monitored, what changes should trigger same-day advice, and how to care for your feet or hands. Discuss smoking, activity, blood pressure, cholesterol, diabetes, and medicines because each may affect vascular risk and the plan for follow-up.
