Medically Reviewed on 4/12/2021

A bunion is a bony prominence in the foot at the base of the big toe or pinky toe. A bunion is medically known as hallux valgus. Bunions are more common in women than in men.

Bunions may or may not cause associated symptoms and signs. Sometimes there is

  • toe pain,
  • swelling,
  • tenderness,
  • redness, or
  • other signs of inflammation of the joint at the base of the toe.

Skin changes such as calluses or blisters can be associated with bunions.

Causes of bunions

Realignment of the joint at the base of the toe causes bunions, which can result from genetic predisposition, abnormalities of the joints such as arthritis conditions, or trauma. Wearing poorly fitting shoes or shoes with a narrow toe box can worsen the condition.
