You have not mentioned where exactly you have developed ulcers. The most common location for ulcers in diabetics is the feet. However, ulcers can also develop in other areas, including the legs, mouth, genitals, and eyelids. The problem is a combination of nerve damage and blood vessel damage. In diabetics, due to poor circulation, even small wounds take a long time to heal, often allowing infection to set in. In addition, due to nerve damage, the patient often does not notice the wound or even the infection till it becomes quite bad. In serious cases, gangrene can set in, which sometimes requires amputation.
To improve your circulation, you should engage in mild, regular exercise. A half hour walk daily should be sufficient, but discuss this with your doctor before you start. Also be sure to wear appropriate, comfortable footwear. Diabetic socks are available, which control moisture, do not restrict circulation, and minimise friction that can cause ulcers. Ensure that your shoes are also comfortable and protect your feet without themselves causing friction. You should wash and dry your feet carefully, and inspect them regularly for any injuries, including minor scratches and blisters. Regarding existing ulcers, it is best to visit a doctor for treatment.
