What Is Plantar Fasciitis?

Plantar fasciitis is one of the most common causes of heel pain, affecting up to 2 million Americans each year. It occurs when the plantar fascia—a thick band of tissue that runs from the heel to the toes—becomes strained or inflamed.

This tissue supports the arch of your foot and absorbs shock when you walk. Repetitive stress, overuse, or prolonged standing can cause small tears, leading to pain and discomfort. 

Symptoms of Plantar Fasciitis

The most common symptom is heel pain, which may feel:

  • Sharp or stabbing
  • Dull and persistent
  • Burning along the bottom of the foot

Pain is typically worse:

  • First thing in the morning (first steps after waking)
  • After long periods of sitting or standing
  • After exercise (rather than during it)
  • When climbing stairs or walking barefoot

Causes and Risk Factors

Several factors can increase your risk of developing plantar fasciitis:

  • Excess body weight (overweight or obesity)
  • Flat feet or high arches
  • Tight Achilles tendon or calf muscles
  • Sudden increase in physical activity or running distance
  • Running on hard or uneven surfaces
  • Wearing unsupportive or worn-out footwear
  • Jobs that require long hours of standing

Heel Spurs and Plantar Fasciitis

Heel spurs are often associated with plantar fasciitis. These are bony growths that develop when the body tries to repair chronic stress in the plantar fascia.

  • Most heel spurs do not cause symptoms
  • They are often found incidentally on X-rays

How Is Plantar Fasciitis Diagnosed?

Diagnosis typically involves:

  • A medical history review
  • A physical exam of the foot and heel
  • Imaging tests (like X-rays) to rule out other conditions such as fractures

Treatment Options

Conservative (Non-Surgical) Treatments

Most cases improve with non-surgical care, including:

  • Rest and activity modification
  • Ice therapy
  • Supportive footwear
  • Custom orthotics (shoe inserts)
  • Night splints to stretch the foot
  • Over-the-counter pain relievers
  • Physical therapy
  • Steroid injections (in more severe cases)
  • Walking boot or cast (for persistent symptoms)

Surgical Treatment

If conservative treatments fail after several months, surgery may be considered.

Plantar Fascia Release

  • Involves cutting part of the plantar fascia to relieve tension
  • Typically performed as an outpatient procedure
  • Recovery may include limited weight-bearing for up to 2 weeks

Gastrocnemius Recession

  • A procedure to lengthen tight calf muscles
  • Reduces strain on the plantar fascia
  • Often recommended when calf tightness is a major contributing factor

Prevention Tips

To reduce your risk of plantar fasciitis:

  • Wear supportive, well-fitting shoes
  • Stretch your calves and feet regularly
  • Increase exercise intensity gradually
  • Maintain a healthy weight
  • Avoid walking barefoot on hard surfaces

FAQ

Rest, ice, stretching exercises, and wearing supportive shoes are the fastest ways to relieve symptoms. Consistency with these treatments is key.

Most cases improve within 6 to 12 months with proper treatment. Mild cases may resolve in a few weeks.

Light walking can be helpful, but excessive walking or standing may worsen symptoms. Supportive shoes are essential.

Yes, many cases resolve without surgery, but ignoring symptoms can prolong recovery.

No. Heel spurs are bony growths, while plantar fasciitis is inflammation of the plantar fascia. They can occur together but are not the same condition.

You should seek medical care if:

  • Pain persists for several weeks
  • Symptoms worsen despite home treatment
  • You have difficulty walking
