You may need to take medicine. In some cases, you may need surgery.Your health care provider will show you how to care for your wound. The basic instructions are:Always keep the wound clean and bandaged to prevent infection. Your provider will tell you how often you need to change the dressing. Keep the dressing and the skin around it dry. Try not to get healthy tissue around the wound too wet. This can soften the health tissue, causing the wound to get bigger. Before applying a dressing, clean the wound thoroughly according to your provider's instructions. You may be able to change your own dressing, or family members may be able to help. A visiting nurse may also help you. PreventionIf you are at risk for ischemic ulcers, taking these steps may help prevent problems:Check your feet and legs every day. Check the tops and bottoms, ankles, heels, and between your toes. Look for changes in color and red or sore areas. Wear shoes that fit properly and do not rub or put pressure on your feet. Wear socks that fit. Socks that are too big can bunch up in your shoes and cause rubbing or the skin, which can lead to a sore. Try not to sit or stand too long in one position. Protect your feet from the cold. Do not walk barefoot. Protect your feet from injury. Do not wear compression stockings or wraps unless told to by your provider. These may restrict blood flow. Do not soak your feet in hot water.Certain lifestyle changes can help prevent ischemic ulcers. If you have a wound, taking these steps can improve blood flow and aid healing.Quit smoking. Smoking can lead to clogged arteries. If you have diabetes, keep your blood sugar level under control. This will help you heal faster. Exercise as much as you can. Staying active can help with blood flow. Eat healthy foods and get plenty of sleep at night. Lose weight if you are overweight. Manage your blood pressure and cholesterol levels.When to Call the DoctorCall your provider if there are any signs of infection, such as:Redness, increased warmth, or swelling around the wound More drainage than before or drainage that is yellowish or cloudy Bleeding Odor Fever or chills Increased painOpen ReferencesReferencesHafner A, Sprecher E.
