A small cut or wound on the foot is easy to ignore. Most people expect it to heal in a few days. When it doesn't, they try basic care and wait longer. But if the wound stays open or slowly worsens, it may not be just a surface problem. Why do some wounds not heal? In many cases, reduced blood flow is the reason. Without proper circulation, even small wounds struggle to close. Is it only related to diabetes? Diabetes is a common cause, but circulation issues can affect healing even otherwise. What are early warning signs? A wound that doesn't improve, changes in skin colour, or reduced sensation in the foot. How is it evaluated? Doctors check blood flow in the leg arteries. Patients are often referred to an interventional radiologist in Pune for detailed assessment. Can it be treated without surgery? In many cases, yes. Improving blood supply through minimally invasive procedures can help the wound heal naturally. If your wound hasn't improved in a few days, you can consult Dr. Santosh B. Patil at Expert-IR and understand what's actually delaying healing.
