An alternate name for this condition is a bunion in which the base of the big toe becomes prominent on the inside of the foot. This bulge is made of bone and soft tissue and is commonly caused by the prolonged wearing of ill fitting shoes, particularly ones that squeeze the toes into unnatural positions. Bunions can be prevented by wearing proper fitting shoes. The symptoms are pain in that area especially when walking, stiffness in the big toe and inflammation of the toe.
The primary mechanism to heal this is via surgery. Without surgery, physical therapy will work to ease the pain, which is limited, but with surgery treatment will include recovery in strengthening the toe and foot.
