Pain is localized below the insertion of the Achilles tendon. Deep palpation of the affected area produces significant discomfort. Calcaneal apophysitis resolves on fusion of the apophyses, which occurs as these patients mature. Diagnosis At history taking, most patients with plantar fasciitis state that they have pain the instant their affected heel touches the floor in the morning. The pain lessens with time and activity.
Most patients experience activity-related discomfort intermittently throughout the day.
By pressing a thumb against the middle of the affected heel, the physician can delineate the area of plantar fascial pain. Pressure similarly applied underneath the calcaneus reveals the area of subcalcaneal pain. Radiographic findings are not specific. As already stated, the correlation between plantar fasciitis and subcalcaneal spurs is not significant. Anteroposterior and lateral views are used to rule out calcaneal stress fracture or other bone abnormalities.
