A bunion is a bony deformity caused by an enlargement of the joint at the base and side of the big toe. Bunions form when the toe moves out of place and starts to point towards the outside of your foot, it can also lead to other toe deformities, such as Hammertoes. The goal for bunion treatment is to relieve the pressure and pain caused by irritations, and second to stop any progressive growth.
Many people with bunions suffer from discomfort and pain from the constant irritation, rubbing, and friction of the enlargement against shoes. The skin over the toe becomes red and tender. Because this joint flexes with every step, the bigger the bunion gets, the more it hurts to walk. Over time, bursitis or arthritis may set in, the skin on the bottom of the foot may become thicker, and everyday walking may become difficult—all contributing to chronic pain.
Wearing shoes that are too tight is the leading cause of bunions. Bunions tend to run in families, usually because of a faulty foot structure such as flat feet.
