Plantar Fasciitis: Symptoms, Causes & PT Treatment
Updated October 20261 minute read
Plantar fasciitis is irritation of the thick band of tissue along the bottom of the foot, and it's the most common cause of heel pain. The signature symptom is sharp heel pain with the first steps in the morning (or after sitting) that eases as you warm up. It's not serious and responds well to load management, calf and foot strengthening, and stretching. Most people improve over a few months without surgery.
What is plantar fasciitis?
The plantar fascia supports the arch of your foot. With overload it becomes irritated where it attaches to the heel, causing pain.
Symptoms
The classic feature is sharp heel pain with the first steps in the morning or after sitting, easing after a few minutes of walking but sometimes returning after long standing or activity. Tenderness is usually at the inner heel.
What causes it / risk factors
A sudden increase in walking or running, tight calves, prolonged standing, unsupportive footwear, and higher body weight contribute.
How it's diagnosed
Diagnosis is clinical from the classic morning-pain pattern and tenderness. Imaging is rarely needed.
Physical therapy treatment
What a PT does. Your therapist reduces the load on the fascia, restores calf and foot strength and flexibility, and addresses footwear and training. Exercises & progression (overview). Calf and foot-muscle strengthening, plantar fascia and calf stretching, and load management; supportive footwear or temporary inserts can help. Recovery timeline. Many cases improve over a few months with consistent care.
Treatment options compared
PT, stretching, and footwear are first-line. Night splints and inserts help some. Injections and surgery are reserved for stubborn cases.
Red flags
Seek care for heel pain after a significant injury, a hot swollen foot with fever, or numbness/tingling suggesting a nerve issue.
