This is the most common biomechanical problem presenting to podiatrists. The Plantar Fascia is a ligament that extends over the full length of the plantar surface of the foot. (see diagram). This ligament is best likened to a piece of rope rather than an elastic band. Poor biomechanical function can result in inflammation and pain anywhere along its length, most commonly in the arch and insertion site at the heel.
Self treatment may include rest, stretches, massage and anti inflammatories.
For short term relief I find the application of a rigid supportive strapping to be extremely reliable. This strapping does need to be kept dry and removed immediately if the area gets itchy as this may indicate sensitivity to the tape or a fungal skin problem.
Long term treatment focuses on functional orthotic devices and footwear advice.
Other treatments may include shock wave therapy or dry needling. Your GP may inject cortisone around the heel insertion site.
