Principal complaint : Pain on under surface of heel after weight bearing.
Pain can be worse when weight is borne after a period of rest (e.g. in morning)
Eases with walking
Passive dorsiflexion of the toes may exacerbate discomfort.
Pathology:
Generally a low-grade inflammatory process involving the plantar aponeurosis with or without the involvement of the perifascial structures.
It can arise from several factors:
mechanical: stress of repetitive trauma (more common)
degenerative
systemic: as an enthesopathy in association with seronegative spondyloarthropathies
