Bunions : Overview, Causes, & Risk Factors

Alternate Names : Hallux valgus

Definition

A bunion is when your big toe points toward the second toe. This causes a bump on the inside edge of your toe.

Overview, Causes, & Risk Factors

Bunions occur more commonly in women and can sometimes run in families. People born with abnormal bones in their feet are more likely to form a bunion. Wearing narrow-toed, high-heeled shoes may lead to the development of a bunion. The condition may become painful as extra bone and a fluid-filled sac grow at the base of the big toe.
