Overview
Plantar fasciitis is inflammation or degeneration of the plantar fascia, a band of tissue supporting the arch of the foot.

Causes and risk factors
Overuse, standing for long periods, poor footwear, obesity, and tight calf muscles can contribute.

Symptoms
Sharp heel pain, typically worse with the first steps in the morning or after rest.

Diagnosis
Clinical exam; imaging is used when symptoms persist or to rule out other causes.

Treatment
Stretching, supportive footwear, orthotics, night splints, NSAIDs, and physical therapy. In resistant cases, injections or other procedures may be considered.

When to seek care
Persistent heel pain affecting walking warrants evaluation.
