PATHOPHYSIOLOGY IN DIABETIC FOOT
Damaged nerves may make it difficult to feel pain, pressure, heat and cold. You may notice irritated skin, pain, or pressure caused by collapsing joints.
Blocked blood vessels bring fewer nutrients to your feet. Without nourishment, sores may not be able to heal.
Weakened bones may slowly shift, causing your foot to become deformed and changing the way your foot distributes pressure.
Collapsed joints, especially a collapsed arch, acn no longer absorb pressure. The surrounding skin may begin to break down.
