Plantar fasciitis is one of the most common causes of heel pain. It involves inflammation of a thick band of connective tissue (the plantar fascia) that runs across the bottom of your foot and connects your heel bone to your toes. Under normal circumstances, your plantar fascia acts like a shock-absorbing bowstring, supporting the arch in your foot. If tension and stress on that “bowstring” become too great, small tears can arise in the fascia. Repetitive stress and tearing can cause the fascia to become irritated or inflamed, although in many cases of plantar fasciitis, the cause isn’t completely clear.
Plantar fasciitis typically causes a stabbing pain in the bottom of your foot near the heel. The pain is usually the worst with the first few steps of the day. It can also be triggered by long periods of standing (especially on hard surfaces) or rising from a seated position. Usually, the pain is worse after exercise, not during it.
