Warning Signs of Circulation and Heart Problems in the Feet

Cold Feet or Toes
Persistently cold feet, even in warm conditions, may indicate poor circulation. A weakened heart

struggles to pump blood efficiently, reducing flow to extremities. This is especially concerning if not linked to cold weather.

Swelling (Edema)
Swelling in the feet or ankles often signals cardiovascular strain. Poor pumping causes blood to pool,

leaking fluid into tissues. It usually appears after standing or sitting for long periods.

While kidney or liver disease can also cause edema, it remains a classic sign of heart failure.

Skin Discoloration
Blue, purple, or pale tones suggest reduced oxygen or blood flow. These changes indicate compromised circulation, which can damage tissues if ignored.

Numbness and Tingling
Pins-and-needles or persistent numbness may stem from peripheral artery disease (PAD),

where fatty deposits narrow arteries. PAD is strongly linked to heart disease and stroke, especially when pain worsens during activity.

Non-Healing Wounds
Sores or ulcers that heal slowly reflect poor circulation. Without enough oxygen and nutrients,

tissues can’t recover, raising infection risk—especially for diabetics.

Pain While Walking (Claudication)
Cramping or pain in calves, thighs, or feet that eases with rest often signals PAD and broader cardiovascular disease.
