A bunion is basically a bump on the inside of the foot, which eventually causes the big toe to point towards your second toe.
Bunions may be hereditary, as they often run in families. In addition, footwear that does not fit properly may cause bunions, especially shoes with tight toe boxes (or heels) Bunions may also be caused by inflammatory conditions such as arthritis.
Conservative management for bunions include stretches/strengthening exercises, custom made orthotics, toe braces, proper fitting footwear and others.
Go see your local manual therapist to have your bunion assessed and managed!
