Plantar Fasciitis vs. Achilles Tendinitis: Where’s Your Heel Pain Coming From?

Heel pain is one of the most common reasons people visit a podiatrist—and understanding exactly where your heel hurts can reveal the cause. Whether it’s sharp pain at the bottom of your heel or aching discomfort behind the heel, two common culprits are usually to blame: Plantar Fasciitis or Achilles Tendinitis.

How Common Is Heel Pain?

According to the American Academy of Orthopaedic Surgeons (AAOS), approximately 2 million people are treated for plantar fasciitis in the U.S. every year, making it the most common cause of heel pain. Meanwhile, Achilles tendinitis accounts for 5-10% of all running injuries, especially affecting active adults and athletes.

Heel Pain in the Front (Bottom) – Plantar Fasciitis

Plantar Fasciitis is caused by inflammation of the plantar fascia, the thick band of tissue that runs along the bottom of your foot, connecting your heel bone to your toes. This condition is typically felt under the heel or arch of your foot.

Symptoms:

  • Sharp, stabbing pain at the bottom of the heel, especially with the first few steps in the morning or after long periods of rest.
  • Pain that may improve as you move around but worsens after prolonged standing or walking.
  • Tenderness when pressing on the bottom of the heel.

Causes and Risk Factors:

  • Repetitive strain from walking, running, or standing for long periods.
  • Flat feet or high arches.
  • Tight calf muscles or Achilles tendon.
  • Obesity (which increases strain on the plantar fascia).

Quick Stat:

According to the National Center for Biotechnology Information (NCBI), plantar fasciitis accounts for about 11-15% of all foot complaints requiring professional care.

Heel Pain in the Back – Achilles Tendinitis

Achilles Tendinitis involves irritation or inflammation of the Achilles tendon, which connects your calf muscles to your heel bone. Pain is typically located at the back of the heel or slightly above it.

Symptoms:

  • Pain and stiffness along the Achilles tendon, especially in the morning or after exercise.
  • Swelling or thickening of the tendon.
  • Tenderness when touching the back of the heel.
  • Pain that worsens with activity, particularly running or climbing stairs.

Causes and Risk Factors:

  • Sudden increase in physical activity, especially running or jumping.
  • Tight calf muscles or poor flexibility.
  • Poor foot positioning.
  • Improper footwear or worn-out shoes.
  • Age—Achilles tendinitis is more common in people aged 30-50.

Quick Stat:

The American Orthopaedic Foot & Ankle Society reports that Achilles tendinitis is especially prevalent among runners and weekend warriors, with men aged 30-49 most commonly affected.

Why a Proper Diagnosis Matters

While both conditions cause heel pain, treatment approaches differ significantly. Misdiagnosis can delay healing and worsen the problem.

  • Plantar Fasciitis often improves with stretching, orthotics, anti-inflammatory treatments, and physical therapy focused on the arch and plantar fascia.
  • Achilles Tendinitis may require calf stretching, eccentric strengthening exercises, address the poor biomechanics of the feet, and changes in footwear or activity.
