Dear sir, I had gone through you query and understood your concerns. The condition is called Diabetic foot ulcer. In diabetics, its most common. In the hospital the following care is taken of course in very good blood sugar control.. The ulcer is usually covered with a protective dressing. A nurse or podiatrist will normally examine, clean and re-dress the ulcer regularly. A podiatrist may need to remove any hard skin that prevents the ulcer from healing. Also, depending on the site and size of the ulcer, they may protect it from further injury by using padding to take the pressure off the area. Antibiotics will be advised for the infection. Sometimes a small operation is needed to drain pus and clear dead tissue if infection becomes more severe. In some cases, the arteries in the legs are very narrow and greatly reduce the blood flow to the feet. In these cases an operation to bypass, or widen, the arteries may be advised. Many foot ulcers will heal with the above measures. However, they can take a long time to heal. In some cases, the ulcer becomes worse, badly infected and does not heal. Sometimes infection spreads to nearby bones or joints, which can be difficult to clear, even with a long course of antibiotics. Occasionally, the tissue in parts of the foot cannot survive and the only solution then is to amputate the affected part. Hope this helps you. Thank you.
