What are the types of leg and foot ulcers?
Neurotrophic ulcers are usually located at increased pressure points on the bottom of the feet. However, neurotrophic ulcers related to trauma can occur anywhere on the foot. They occur primarily in people with diabetes although they can affect anyone who has an impaired sensation of the feet. The base of the ulcer is variable, depending on the patient’s circulation. It may appear pink/red or brown/black. The borders of the ulcer are punched out, while the surrounding skin is often calloused. Neuropathy and peripheral artery disease often occur together in people who have diabetes. Nerve damage (neuropathy) in the feet can result in a loss of foot sensation and changes in the sweat-producing glands. As a result, a person may not feel the development of foot calluses or cracks, increasing the risk of injury or infection. Symptoms of neuropathy include tingling, numbness, burning or pain. It is easy to understand why people with diabetes are more prone to foot ulcers than other patients.
