One of the most effective treatment options for plantar Fasciitis is stretching. Tightness if the achilles tendon and the calf muscles, increases the prevalence of plantar Fasciitis. This is due to tightening in these muscles, which increases dorsiflexion (upward movement) of the large toe and stretches the plantar fascia causing it to inflame.
Therefore it makes sense that reduction of the tightness of the achilles tendon and calf muscles will have a positive effective on heel pain. Your stretching exercises should concentrate on the Achilles tendon and calf muscles group. These exercises can be done at the comfort of your home to treat the condition and lessening the chance of recurrence plantar fasciitis pain.
