Quick guide
This page provides general health information and does not diagnose an individual condition. Persistent, worsening or concerning symptoms should be assessed by an appropriately qualified health professional.

Understanding the problem

A bunion, or hallux valgus, develops when the big toe gradually angles toward the lesser toes and the first metatarsal shifts in the opposite direction.

Contributing factors

What can you do?

When not to wait
A suddenly hot, red and intensely painful big-toe joint should be assessed because gout, infection and other acute conditions can resemble bunion pain.
