This is my uncle who kept on complaining about not able to walk.. Showed him to a doctor he said giving him medicine if doesn't work then need to oparate but his financial conditions are not as such that he could afford an expensive operation..

The picture shows the current situation of his leg and feet it's terrible, please tell me why is this happening so?
