Overview of Plantar Fasciitis
Plantar fasciitis is inflammation of the plantar fascia, a band of tissue on the bottom of the foot that connects the heel to the base of the toes and forms the arch. It causes pain along the bottom of the foot and the front of the heel, which can make it hard to put weight on the foot. The pain is often worst first thing in the morning and eases a little as you walk, but it may flare after exercise or long periods of standing. Heel spurs are one possible complication.
Repeated pressure on the heel or an uneven step can strain the fascia and cause small tears, leading to inflammation and pain. Common causes include feet that roll inward too much, high arches, a tight Achilles tendon, hard or uneven surfaces, and running or other sports. Poorly cushioned shoes, extra weight, and aging can also play a role, and in rare cases a foot injury can trigger it.
Pain Often Hits With the First Steps of the Day
Many people feel the sharpest heel pain when they first stand up in the morning or after sitting for a long time. The pain usually eases once you start moving.
