The first signs of a leg ulcer can vary, depending on the cause of the ulcer. Common signs include redness, swelling, warmth, and tenderness at the site of the ulcer. The area may also be painful or itchy. In some cases, there may be visible damage to the skin, such as an open sore, a blister, or a scab. In other cases, the ulcer may be hidden beneath the skin.
Some people may notice a discharge of fluid from the ulcer. This can range from a light pinkish fluid to a dark, foul-smelling discharge. Other signs may include tightness in the affected area, or a sensation of burning or throbbing pain.
If the ulcer is caused by a condition such as diabetes or peripheral arterial disease, other symptoms may also be present. These may include a weakened pulse in the affected area, or a feeling of numbness or weakness in the legs. If any of these symptoms are present, it is important to seek medical advice immediately.
