Bunion exercises can ease the pain caused by bunions, a painful toe joint deformity. You develop a bunion when pressure pushes the big toe toward the second toe. When the top of the toe moves, it forces the bone in the joint at the base of the toe to shift outward. As the bone shifts, it causes a lump on the side of your foot. Without treatment, bunions gradually enlarge and become inflamed.
