What it is
A problem that occurs when the bone at the base of the big toe shifts and the big toe moves in toward the other toes. A painful bump may form on the outside of the bone.

Why you get it
Mostly because of faulty foot biomechanics that are inherited. Narrow shoes with a small toe box can irritate and worsen the bunion, but usually are not the primary cause.

Pads. Orthotics (to realign feet). Anti-inflammatory medication. Cortisone injections. Physical therapy. Wider shoes. Surgical removal is a last resort.

Wear shoes with a wide toe box and low heels. If you have flat feet, consider orthotics.
