A tingling or “pins and needles” sensation that occurs without warning—or gets worse with activity—could be a sign of peripheral artery disease (PAD), a condition where narrowed arteries reduce blood flow to the limbs.
PAD is strongly linked to heart disease, and often serves as a warning sign that the arteries near the heart may also be blocked.
You may notice:
- Numbness in the toes or soles
- A burning or prickling sensation
- Relief when you stop walking or elevate your feet
If left untreated, PAD can increase the risk of heart attacks and strokes significantly.
5. Sores or Wounds That Won’t Heal
Have you noticed cuts, blisters, or sores on your feet that seem to linger or resist healing?
Slow-healing wounds, particularly on the toes or heels, can indicate chronic poor circulation, which deprives the skin of the nutrients and oxygen needed to repair itself.
This symptom is especially dangerous for people with diabetes, but even in non-diabetics, it can signal early heart disease or vascular damage. Over time, these untreated wounds can lead to infections or even amputations in severe cases.
