What is Plantar Fasciitis?

A clear, jargon-free explanation of what's happening in your body

Plantar fasciitis occurs when the thick band of tissue connecting your heel to your toes becomes inflamed. The signature symptom is sharp heel pain on your first steps in the morning — pain that eases after a few minutes but returns after long periods of standing or activity.

The good news: plantar fasciitis is one of the most well-understood conditions in podiatric medicine, with a wide range of effective treatments available — most of which are covered by insurance. The key is getting an accurate diagnosis early, before the condition becomes chronic.

What Causes Plantar Fasciitis?

Understanding the root cause is the first step toward effective treatment

Overuse & High Impact

Running, jumping, and standing on hard surfaces for long periods put repetitive stress on the plantar fascia, leading to small tears and inflammation.

Poor Footwear

Flat shoes, flip-flops, and worn-out athletic shoes lack arch support and shock absorption — the two things the plantar fascia needs most.

Foot Mechanics

Flat feet, high arches, or an abnormal gait pattern can distribute weight unevenly across the plantar fascia, accelerating wear.

Tight Calf Muscles

Limited ankle flexibility puts extra strain on the plantar fascia during walking and running. Calf and Achilles stretching is often the first line of treatment.

Treatment Options

Ranked by effectiveness — most patients start with conservative options and escalate only if needed

Custom Orthotics

✓ Usually covered ⏱ 4-8 weeks

Effectiveness

85%

Prescription insoles correct your specific foot mechanics. Far more effective than OTC insoles and usually covered by insurance.

Physical Therapy

✓ Usually covered ⏱ 6-12 weeks

Effectiveness

80%

Targeted stretching and strengthening protocols, including the eccentric heel drop exercise — the gold standard for plantar fasciitis.

Corticosteroid Injection

✓ Usually covered ⏱ 1-3 weeks

Effectiveness

70%

Fast-acting anti-inflammatory injection for moderate-to-severe cases. Typically used after conservative treatments.

Shockwave Therapy

Out of pocket ⏱ 3-6 weeks

Effectiveness

75%

Non-invasive ultrasound stimulates healing in chronic cases. Often covered after 6 months of failed conservative treatment.

Night Splints

✓ Usually covered ⏱ 4-12 weeks

Effectiveness

65%

Keeps the plantar fascia gently stretched overnight, dramatically reducing morning pain.

PRP Therapy

Out of pocket ⏱ 6-12 weeks

Effectiveness

78%

Platelet-rich plasma from your own blood injected to accelerate tissue repair. Emerging evidence strongly supports its use.

Frequently Asked Questions

Real questions from patients — answered without the medical jargon

How long does plantar fasciitis actually take to heal? ▼

With consistent treatment, most cases resolve in 6–18 months. The patients who heal fastest start treatment early, wear supportive footwear consistently, and do their stretching exercises daily. Patients who wait 6+ months before seeing a doctor average 2–3x longer recovery times.

Can I run with plantar fasciitis? ▼

In most cases, yes — with modifications. Reduce mileage by 50%, avoid hills and speed work, replace your running shoes if they're over 400 miles, and add a stretching routine before and after runs. If pain is above a 4/10 during running, take a week off. Running through severe pain risks converting an acute injury into a chronic one.

What's the difference between plantar fasciitis and a heel spur? ▼

They often occur together but are different things. Plantar fasciitis is inflammation of the plantar fascia. A heel spur is a calcium deposit that forms on the heel bone — often as a result of chronic plantar fasciitis. Heel spurs themselves are usually painless; the pain comes from the inflamed fascia around them. Treatment is the same for both.

Do I really need to see a podiatrist or can I treat it myself? ▼

For symptoms lasting less than 4 weeks, self-treatment (stretching, OTC insoles, ice, rest) is reasonable. If you're still in pain after 4 weeks, see a podiatrist. Left untreated, plantar fasciitis commonly becomes chronic — and chronic cases take 3–5x longer to resolve than acute ones. A podiatrist visit also rules out other causes of heel pain like stress fractures or nerve entrapment.

Is surgery ever necessary? ▼

In fewer than 10% of cases, after 12+ months of failed conservative treatment. Plantar fasciotomy (partial release of the fascia) has a 70–80% success rate but carries risks including arch collapse and nerve damage. Always get a second opinion before agreeing to surgery, and make sure you've completed a full course of physical therapy first.
