🚨 When it’s an emergency
Get urgent medical help if a foot suddenly becomes severely painful, cold, pale/blue, numb, or difficult to move. A sudden loss of blood flow can threaten the limb.

If you have diabetes, check your feet every day for cuts, blisters, redness, swelling, or sores, because nerve damage can reduce your ability to feel an injury and poor blood flow can slow healing.

Bottom line: These symptoms don’t automatically mean diabetes or blocked arteries. Foot problems have many possible causes, so persistent, worsening, or unexplained changes are best evaluated by a healthcare professional.
