Plantar Fasciitis is the term used to describe pain on the sole of your foot, typically close to your heel. It is a condition that develops from overuse and increased weight-bearing loading stress on your feet. Your 'Plantar Fascia' is a thick connective tissue, much like a bed sheet pulled tight, that supports the arch of your foot. With overuse or strain, it can becomes tight and inflamed at its attachment points where it pulls on the bone.
A key complaint of people who suffer from Plantar Fasciitis is pain worst after rest. For Example - When they first get out of bed, or after prolonged sitting, the first few steps of walking are the worst, and then it slowly warms up and becomes more tolerable.
Physiotherapy can help by taping your foot to offer support, releasing the tightness in the plantar fascia, ultrasound therapy and a few stretches to ease your pain.
