Why some wounds do not heal

Several factors can work together: reduced sensation that hides pressure and injury, poor blood flow, infection, repeated pressure on the same spot, foot deformities, and elevated blood sugar. Addressing only the surface of the wound without these causes often leads to recurrence.

Warning signs to act on

Any open sore on the foot that is not clearly improving
Redness, warmth, swelling or drainage around a wound
Odor, or a wound that looks deeper than before
Skin that turns dark, blue or black
Fever or chills together with a foot wound

Fever, spreading redness or a rapidly worsening wound can signal a serious infection and need urgent evaluation.

How wounds are treated

Careful cleaning and removal of unhealthy tissue
Dressings suited to the wound
Offloading, meaning taking pressure off the area with special shoes, boots or devices
Treatment of infection, including evaluation for bone involvement
Assessment of circulation, with referral to vascular specialists when needed
Blood sugar management in coordination with your other doctors

The role of surgery

When a bony prominence, deformity or tight tendon keeps causing pressure and breakdown, surgical correction can remove the cause so the wound can heal and stay healed. In more advanced infections, surgery may be needed to remove infected tissue. The aim throughout is to preserve as much of a functioning foot as possible.

Prevention

Check your feet daily, wear protective footwear and never go barefoot, and report any new sore early. If you have diabetes, regular foot examinations are an important part of staying ahead of problems.

What to expect at your visit

A first visit typically includes a review of your symptoms and history, an examination of the foot and ankle (often including how you stand and walk), and imaging such as X-rays when needed. Dr. Ajdari will explain your options, including non-surgical care, so the two of you can choose a plan that fits your goals.
