4. Numbness and Tingling
Persistent numbness or pins-and-needles sensations may be linked to peripheral artery disease (PAD), where fatty deposits in leg arteries restrict blood flow. PAD is closely associated with heart disease and stroke, making these symptoms particularly important to monitor. Pain or numbness that worsens during activity is especially concerning.
5. Non-Healing Wounds
Sores, blisters, or ulcers that heal slowly—or not at all—can indicate poor circulation. Without sufficient blood flow, tissues lack the nutrients and oxygen needed for healing. This is particularly risky for individuals with diabetes, increasing the likelihood of infections or serious complications.
6. Pain While Walking (Claudication)
Cramping or pain in the feet, calves, or thighs during walking, which eases with rest, is known as claudication. It often results from PAD and signals significant circulation issues. Claudication can be a strong predictor of underlying cardiovascular disease.
