Do you often feel that one foot is colder than the other? Or maybe your lower legs are consistently chilly even in warm weather?
This temperature difference may be a sign that blood is not flowing properly through blocked arteries.
Quick Self-Check
Touch both feet with your hands. If one feels significantly colder, it could be a warning worth mentioning to your doctor.
4. Slow-Healing Sores or Wounds
Healthy blood flow is essential for healing cuts, scrapes, and blisters. When circulation is restricted, wounds on the legs and feet may heal very slowly.
Why This Matters
Open sores that don’t heal properly increase the risk of infection. This is especially concerning for people with diabetes, who may already have reduced sensitivity in their feet.
5. Changes in Skin Color
Blocked arteries can also cause noticeable changes in the skin. You may see:
- Pale or bluish skin tone
- Shiny, thin skin
- Darkened areas around the toes or feet
