Plantar fasciitis is, by far, the most common cause of heel pain, but other causes are possible. A few other causes may include fractures, bone bruises, and nerve entrapment of the inferior calcaneal nerve. Susz Podiatry & Wound Care offers on-site diagnosis using a physical exam, symptom evaluation, and imaging tests. While bone spurs show up on X-rays in many people with plantar fasciitis, the bone spurs aren’t the cause of the pain. They’re usually a reaction to plantar fasciitis.
