What are the treatment options for plantar fasciitis?

Treatment of Plantar Fasciitis

Start with plantar fascia-specific stretching and calf stretching exercises as the cornerstone of treatment, combined with ice massage, over-the-counter heel cushions, and NSAIDs, then escalate progressively to more invasive interventions only if there is no improvement after 6 weeks. 1

Initial Conservative Treatment (First 6 Weeks)

The American Academy of Family Physicians emphasizes that regular stretching of the calf muscle and plantar fascia is the single most important intervention for plantar fasciitis 1. This should be implemented immediately as the foundation of treatment.

Core Initial Interventions:

• Plantar fascia-specific stretching exercises performed regularly to reduce tension on the fascia 2, 1
• Calf muscle stretching to address limited ankle dorsiflexion, a key risk factor 2, 1
• Ice massage (cryotherapy) applied directly to the affected area to reduce pain and inflammation 2, 1
• Over-the-counter heel cushions and arch supports to provide mechanical relief and cushion the heel 2, 1
• Oral NSAIDs for pain control, though evidence shows only modest benefits 2, 1, 3
• Foot taping and padding for additional support 2, 1

Activity Modifications:

• Avoid flat shoes and walking barefoot both indoors and outdoors, as this exacerbates the condition 2, 1
• Activity limitation to decrease cyclical repetitive loading of the plantar fascia 4
• Weight loss if indicated to reduce mechanical stress 2

Common Pitfall:

Do not delay treatment initiation—symptoms resolve more quickly when treatment begins earlier after symptom onset 5. With proper treatment, 80% of patients improve within 12 months 6.

Intermediate Treatment (After 6 Weeks Without Improvement)

If there is no improvement after 6 weeks, refer to a podiatric foot and ankle surgeon and escalate treatment 1.

Advanced Conservative Measures:

• Customized orthotic devices (more effective than over-the-counter devices) 1
• Night splints for passive dorsiflexion stretching 1
• Limited corticosteroid injections in appropriate patients, though effects are short-lived and carry risks of fat pad atrophy and plantar fascia rupture 1, 4
• Immobilization with a cast or fixed ankle walker device during activity 1
• Physical therapy with specific modalities 1

Diagnostic Imaging for Persistent Cases:

• Ultrasonography is a reasonable and inexpensive diagnostic tool for patients with pain persisting beyond 3 months despite treatment, with 80% sensitivity and 88% specificity 1, 6
• MRI is the most sensitive imaging study, reserved for recalcitrant cases or to rule out other heel pathology 1

Treatment for Severe Refractory Cases

For severe cases with disabling symptoms that significantly impact quality of life and function after exhausting conservative options:

• TNF inhibitors should be considered for severe enthesitis (including plantar fasciitis) that has failed other therapies, based on GRAPPA Treatment Recommendations Committee guidelines 2
• Ultrasonography-guided focal extracorporeal shock wave therapy is useful for chronic plantar fasciitis 4
• Endoscopic fasciotomy may be required in patients who continue to have pain limiting activity and function despite exhausting all nonoperative treatment options 6

Important Caveat:

Approximately 90% of patients ultimately respond to nonsurgical treatment, so surgical intervention should be reserved only for truly refractory cases 7. The natural history suggests this is largely a self-limited condition when managed appropriately 7, 5.
