Understanding Foot Pain in Kids: Differentiating Sever's Disease, Achilles Tendonitis, and Plantar Fasciitis

By

Children are often active, but when foot pain strikes, it can quickly limit their play and physical activity. Three common causes of foot pain in young kids are Sever's disease, Achilles tendonitis, and plantar fasciitis. Recognizing the signs of each condition and knowing how to manage them can help alleviate pain and prevent future issues.

1. Sever's Disease: Heel Pain Due to Growth Spurts

  • What It Is: Sever’s disease, or calcaneal apophysitis, is a common cause of heel pain in growing children, especially those involved in sports like soccer, gymnastics, or running. It typically occurs during growth spurts (ages 8-14) when the heel bone grows faster than the surrounding muscles and tendons, causing tightness and pulling.
  • Symptoms: Pain at the back of the heel, particularly after physical activity. The pain is often worse when pressing on the sides of the heel or after prolonged standing.
  • How to Help:
    • Rest and limit high-impact activities.
    • Ice the area for 15-20 minutes after activities.
    • Stretching exercises for the calf muscles and Achilles tendon can help reduce tension.
    • Orthotic inserts or heel cups can provide additional heel support, cushioning the impact on the foot.

2. Achilles Tendonitis: Overuse Injury at the Back of the Heel

  • What It Is: Achilles tendonitis is an inflammation of the Achilles tendon, the large tendon at the back of the ankle. Although more common in teens, it can affect younger children involved in intense sports or who wear improper footwear.
  • Symptoms: Pain and tenderness along the back of the ankle, especially after activity. Swelling and stiffness may occur, and the pain can worsen in the morning.
  • How to Help:
    • Encourage rest and reduce high-impact sports temporarily.
    • Apply ice to the area for 15-20 minutes post-activity.
    • Stretch the Achilles tendon and calf muscles gently, especially before and after activities.
    • Ensure supportive footwear with a slight heel lift to relieve tension on the Achilles tendon.

3. Plantar Fasciitis: Heel Pain on the Bottom of the Foot

  • What It Is: Plantar fasciitis involves inflammation of the plantar fascia, a thick band of tissue running along the bottom of the foot. While common in adults, plantar fasciitis can also affect children, particularly those with flat feet or very high arches.
  • Symptoms: Pain in the heel, especially upon waking or after long periods of inactivity, often described as a sharp or stabbing sensation on the bottom of the foot.
  • How to Help:
    • Foot and calf stretching exercises can improve flexibility.
    • Rolling the foot over a frozen water bottle for a few minutes can provide relief.
    • Supportive shoes or orthotics help to cushion the foot and support the arch.

How to Tell Them Apart

  • Sever’s Disease: Pain primarily at the back and sides of the heel, worsens with activity.
  • Achilles Tendonitis: Pain along the Achilles tendon at the back of the ankle, typically increases with tightness or movement.
  • Plantar Fasciitis: Sharp, stabbing heel pain on the bottom of the foot, especially noticeable first thing in the morning.

When to See a Professional

Persistent pain, especially if it limits a child’s daily activities, should be evaluated by a healthcare provider. Chiropractic care, physical therapy, and custom orthotic solutions can also help support a child’s foot health and alignment. Early intervention and consistent management can help alleviate pain and keep kids moving confidently.
