Plantar Fasciitis: Symptoms, Causes and When to Seek Help

Plantar fasciitis is irritation of the plantar fascia, most often where it attaches to the heel bone. It is typically an overuse condition, though it can develop after a change in activity, footwear or body weight. Most cases settle over months, though symptoms can be persistent.

Symptoms may include sharp or aching pain at the bottom of the heel, worst with the first few steps in the morning or after long periods of rest. Pain often eases with gentle movement but may return after prolonged standing or exercise. Symptoms can vary from person to person and are usually one-sided.

Risk factors can include running, jobs involving long hours on the feet, sudden increases in training, tight calf muscles, flat or high-arched feet, being overweight, and unsupportive footwear. It is more common in adults between the ages of 40 and 60.

Seek medical advice if heel pain lasts more than a few weeks, is severe, or is not improving with basic self-care such as supportive shoes and stretching. Assessment is also appropriate if there is numbness, significant swelling, redness or a history of trauma to the heel.
