Why can a bone appear on the big toe

Wrong shoes. Shoes with a narrow toe and heel. They shift the support to the big toe, due to which the load on it increases and the body itself "grows" the bone for greater stability. The bone on the thumb can be the result of genetics and diseases that are inherited. Other causes of bunions include foot injuries, excess weight, and hormonal imbalances. The latter can appear during puberty, pregnancy, lactation and menopause. By itself, it is not dangerous. There are many ways to get rid of this pathology, but the most effective is the operation.
