Skin ulcer is particularly the area of the skin that has broken down and that you are able to see the underlying tissue. It is usually seen that skin ulcers usually appear on the feet or in the lower legs. Skin generally heals quickly when it undergoes a cut, but with some people who suffer from diabetes the skin on the foot is unable to heal properly and that gradually becomes prone to ulcers. This can happen after small injuries like stepping on a stone with bare feet.
There are different types of foot ulcers like venous ulcers that are situated below the knee and are towards the inner part of the leg right above the ankle. The venous ulcer is usually irregular in shaped and the skin surrounding becomes discolored and is swollen. The ulcer will also feel warm. The skin above the ulcer appears to be tight and shiny depending on the swelling or the edema. It shows purple or brown discoloration, which is called as stasis skin changes.
Another type of ulcer is the neurotrophic ulcer. This ulcer is generally found at increased pressure points at the sole. But, if the neurotrophic ulcer is associated with trauma, then it can occur at any point of the foot. These are seen to occur mainly in people suffering from diabetes, but they can occur in anyone who seems to have an impaired sensation in the feet. Diabetes results in a lot of nerve damage and also hampers the vascular supply in the legs and feet. People suffering from neuropathy have no or reduced sensation and will be unaware of any injury caused to their feet.
Continuing to walk on injured feet can result in further damage and a small lesion can become a serious affair. Giving attention to simple things like examining your foot every time and also checking shoes for any harmful object like stone, glass, pins, or the like before wearing them can prevent such things from happening. It is also important to avoid walking barefoot. It is also seen that patients with such problems are of the older generation and are unable to see properly making it difficult for them. Nerve damage because of diabetes results in complete loss of sensation or an altered feeling that prevents the person from distinguishing any damage caused. This can result in loss of skin, blisters and occurrence of ulcers.
Doctors usually recommend antibiotics for a wound that is fresh. An anti-platelet or anti-clotting drug can be given to prevent formation of blood clot and the doctor can also suggest topical applications for wound care and compression garments. As a thumb rule it is better to control diabetes and take proper precautions so that you are less likely to develop any complication like foot ulcer. You can also get appropriate treatment for controlling blood pressure, cholesterol and also for reducing other risk factors that are bound to worsen your condition. Keep a check on your feet and keep looking for any wounds or shoe bites that would have occurred. If you observe any injuries then, you should report it to your physician immediately.
