What Causes Plantar Fasciitis to Flare Up?
Plantar fasciitis is one of the most common causes of heel and foot pain. It occurs when the plantar fascia, a band of tissue that runs along the bottom of the foot, becomes inflamed. Certain factors can cause plantar fasciitis to flare up, including lots of physical activity, wearing shoes without proper support, or rapid weight gain.
