Definition: Bunions are a common problem that most people experience as a bony protuberance at the base of the big toe. The problem, however, is more complicated than simply a bump. The most common cause of bunions is due to the big toe angling in towards the other toes, a condition called hallux valgus. Bunions are most common in women, and the cause is usually wearing unsuitable footwear.
