A bunionette is a small bump on the outside of your foot where your little toe meets your foot. Just like a bunion on your big toe, a bunionette is formed when your little toe turns inward and the joint is forced outward by a misalignment of the bones in the foot. If you wear shoes with a wide toe box or are often in sandals or open-toed shoes, you might not even realize you have bunionette. Most people don't notice the deformity until it becomes painful.
If the bunionette starts to rub against the inside of your shoe, it can become swollen, red, and painful. The more misaligned the bones are, the further out the bunionette will be and the more painful it will become. The only way to permanently correct the deformity is with surgery, but conservative measures can be used to manage the discomfort until it becomes unbearable.
