Foot Injuries and Disorders
Each of your feet has 26 bones, 33 joints, and more than 100 tendons, muscles, and ligaments. No wonder a lot of things can go wrong. Here are a few common problems:
- Bunions - hard, painful bumps on the big toe joint
- Corns and calluses - thickened skin from friction or pressure
- Plantar warts - warts on the soles of your feet
- Fallen arches - also called flat feet
Ill-fitting shoes often cause these problems. Aging and being overweight also increase your chances of having foot problems.
