Achilles Tendinitis

The Achilles tendon attaches the calf muscle to the heel bone. Achilles tendinitis is a repetitive strain (overuse) injury involving lower leg muscles and tendons at the point where they attach to the bone, resulting in pain at the back of the ankle. Chronic overuse can lead to small tears within the tendon causing long-term weakening, making the tendon susceptible to rupture, which could result in a need for surgery. See our Achilles Tendinitis exercises for more information on how to help ease your pain.

Causes of Achilles Tendinitis

Lack of flexibility and overpronation are two of the most common causes of chronic Achilles tendinitis. Achilles tendinitis may be caused by a single incident of overstressing the tendon, or it may result from a series of stresses that produce small tears over time (overuse). Other risk factors and causes of Achilles tendinitis include:

  • Poor conditioning
  • Overuse
  • Stressful surfaces
  • High-heels

Achilles Tendinitis Symptoms

  • Pain in the heel and tendon when walking/running
  • Pain and stiffness in the morning
  • Tendon hurts to touch or move
  • Warm or swollen area around heel and tendon
  • Trouble standing up on one toe

Prevention and Treatment for Achilles Tendinitis

As with all injuries, prevention is your best defense especially with injuries that are as painful and inconvenient as Achilles tendinitis.  Options for how to prevent Achilles tendinitis include:

  1. Stretching- Stretching properly, starting slowly, and increasing gradually will be critical if you want to avoid Achilles tendinitis.  To help maintain flexibility in the ankle joint, begin each day with a series of stretches and be certain to stretch prior to, and after, any exercise or excessive physical activity.
  2. Orthotics and Heel Support-Bio-mechanically engineered inserts and heel cups can be placed in your shoes to correct misalignments or bolster the support of your foot and are available without a prescription.  The temporary heel padding that these provide reduces the length that the Achilles tendon stretches each time you step, making it more comfortable to go about your daily routine.
  3. Proper Footwear- Low-heeled shoes with good arch support and shock absorption are best for the health of your foot.  Look into heel wedges and other shoe inserts to make sure that your everyday foot mechanics are operating under ideal conditions.

Treatment options for Achilles tendinitis are focused on relieving suffering and promoting healing.  If high heels are worn every day, stretching should be done every morning and night to keep the Achilles tendon lengthened.
