Plantar Fasciitis Causes
Many things can cause irritation and inflammation, but it's most commonly caused by overuse. Excessive downward force is another common cause for plantar fasciitis. Repeated tearing of the plantar fascia affects its ability to support the arch of the foot. If the plantar fascia is strained by the way you walk or by repeated stress, it can become weak, swollen and irritated and will hurt to walk or stand.
