What is it?
The condition is caused by irritation to the attachment of this tissue to the heel bone (calcaneus) at the Medial (inside) insertion (attachment point). A common reason for this irritation is increased stretch to the medial (inner) border of the tissue caused by over pronation but those with abnormal foot biomechanics such as over supination and pes cavus may also be susceptible to this condition. There can sometimes be an associated heel spur.
These include: pain on the underside of the heel at its inner border where it joins the arch which is often worse on placing the foot to the ground when arising from bed in the morning or when standing after a period of rest, tenderness to palpation (application of gentle pressure) at the medial (inside) attachment point of the plantar fascia to the calcaneus.
• Functional Foot Orthotics to realign the foot and improve the biomechanics will assist.
• The use of specifically placed shock absorbing materials to help reduce shock loading to the foot may also be beneficial.
