When Charcot causes bones to break, the foot will become inflamed. The first signs of Charcot are a foot that is red, hot, and swollen. Sometimes, patients who don’t normally have much feeling will complain of pain. Later on, as the foot collapses, large deformities may become present. Over time, these deformities can make it difficult to fit into shoes, difficult to walk, and can lead to ulcers on the foot.
