Common causes of foot pain include plantar fasciitis and heel spurs. Any part of the complex structure of the foot may be affected, from the toes to the heel.
Plantar fasciitis, a common cause of heel pain, is the term for inflammation of the plantar fascia, a band of thick tissue that connects the heel bone to the toes. It runs across the bottom of the foot and, when inflamed, creates a stabbing pain that tends to be worst in the morning or after periods of inactivity. It frequently affects runners or people who are overweight or wear shoes with poor support.
Heel spurs are calcium deposits that cause a bony growth that typically protrudes from the heel bone and points toward the foot’s arch. One of 10 people have heel spurs, and about five percent of them experience pain. About half the people with plantar fasciitis also have heel spurs.
