Plantar Fasciitis

Plantar fasciitis produces a characteristic pattern of pain that distinguishes it from other causes of heel pain. Patients often describe the discomfort as a sharp, stabbing, or burning sensation originating at the bottom of the heel, typically worse at specific points in the day rather than constant throughout. **Common symptoms include:**

• First-step morning pain — the hallmark symptom; severe heel pain with the first few steps out of bed, caused by the fascia contracting overnight and being abruptly loaded
• Pain after prolonged rest or sitting ("post-static dyskinesia") — similar start-up pain after any period of inactivity during the day
• Point tenderness at the medial heel — reproducible tenderness when pressing directly on the inner aspect of the heel bone
• Pain that initially improves with walking but returns and worsens with prolonged activity (walking, running, or standing for extended periods)
• Increased pain when walking barefoot or on hard surfaces without cushioning
• Worsening with stair climbing — particularly when pushing off the ball of the foot going upstairs
• Occasional tightness or stiffness in the arch or calf, particularly in the morning

Plantar fasciitis is primarily a clinical diagnosis, meaning it is established through a detailed patient history and a focused physical examination. No imaging is required in most straightforward cases.

History and Physical Examination

Our podiatrists will ask about the onset, location, and character of your pain; your occupation and activity level; footwear habits; and prior treatments. On physical exam, the most reliable finding is point tenderness on palpation of the medial calcaneal tubercle, the precise origin of the plantar fascia. Dorsiflexion of the toes (the Windlass test) typically reproduces or intensifies the pain by tensioning the fascia. Reduced ankle dorsiflexion from gastrocnemius or Achilles tightness is also assessed, as it is both a risk factor and a driver of treatment planning.

Imaging

• X-ray (weight-bearing foot series) — obtained to rule out a heel spur, calcaneal stress fracture, or other bony pathology. Notably, a heel spur is present in up to 50% of patients with plantar fasciitis but is also found in asymptomatic individuals; the spur itself is generally not the source of pain.
• Diagnostic ultrasound is used to measure plantar fascia thickness (>4 mm is consistent with pathology), visualize structural changes at the insertion, and confirm the diagnosis when the clinical picture is ambiguous. Ultrasound also guides precise injection therapy.
• MRI: rarely needed for typical presentations; reserved for cases where stress fracture, tarsal tunnel syndrome, or soft-tissue mass is suspected, or when the diagnosis remains unclear after initial workup.

Conservative Care Timeline

The majority of patients (more than 90%) achieve satisfactory pain relief with 6–12 months of consistent conservative treatment. Adherence to stretching programs, footwear modification, and activity adjustment is the single most important predictor of successful non-operative outcome. Early initiation of treatment is associated with shorter recovery.

After Corticosteroid Injection

Pain relief typically begins within 3–7 days and peaks at 3–4 weeks. Patients are advised to limit high-impact activity for 1–2 weeks following injection. Because repeated injections carry rupture risk, they are not administered more frequently than every 3–4 months.

After PRP Injection

PRP has a different recovery curve than corticosteroid: pain may temporarily increase for 1–2 weeks as the tissue inflammatory-reparative response is initiated. Meaningful improvement is typically seen at 6–8 weeks, with continued benefit at 6 and 12 months as collagen remodeling progresses. Patients are advised to continue stretching and avoid high-impact loading for 2–4 weeks post-injection.

After ESWT

Most patients experience progressive improvement over 6–12 weeks following their final ESWT session. Mild soreness at the treatment site is expected for several days after each session; there is no required downtime.

After Plantar Fascia Release Surgery

Recovery from endoscopic release typically involves:

• Non-weight-bearing or protected weight-bearing for 2–4 weeks
• Return to normal footwear at 4–6 weeks
• Return to low-impact activity at 6–8 weeks
• Return to running and high-impact sports at 3–4 months
• Formal physical therapy for range of motion, strengthening, and gait rehabilitation
