Bunions are hereditary and quite often they are exasperated by footwear. Bunions often form because of a mechanical imbalance called overpronation which is a biomechanical condition when your arches collapse and roll in when walking. This imbalance puts more pressure on the big toe joint resulting in a misalignment of the joint.
Effective treatment will address the biomechanical condition (overpronation) with custom orthotics to prevent the bunion from worsening. Custom orthotics will redistribute pressure away from the big joint toe. Anti-inflammatories may be prescribed for pain. Proper footwear may also be recommended.
If left untreated, the big toe joint may completely dislocate, needing surgical correction.
