If you can still flex your toe, your doctor may suggest exercises to stretch and strengthen the muscles. They include scrunching a towel and picking things up off the floor with your toes.
Wearing roomy shoes can also help. They should be at least a half-inch longer than the big toe. Your doctor may recommend wearing shoe inserts or pads to relieve some of the pressure.
Over time, the bend in your toe may become permanent and rigid. These cases are more serious. You may need surgery.
