Causes
The exact cause of achilles tendinopathy is not known. It is thought to be from overuse from:
- Increasing speed or running long distances too quickly
- Suddenly adding hills or stair climbing to an exercise routine
- Stressing the calf muscles too soon after taking time away from exercising
- Putting sudden stress on the calf muscles when they are not ready for stress
Risk Factors
Achilles tendinopathy is more common in men and older adults. Other things that may raise the risk are:
- Certain lower leg problems, such as lack of flexibility, poor range of motion, or a foot that turns inward too much
- Certain health problems, such as obesity and diabetes
- A poor training program, such as activity on hard surfaces or hills
- Wearing poor footwear
- Certain medicines, such as corticosteroids
Symptoms
Symptoms of achilles tendinopathy may include:
- Pain and stiffness above the heel bone
- Problems that happen when bearing weight after rest, such as after sleeping
- Swelling at the tendon
- Problems wearing shoes
- Decreased strength in the tendon
Diagnosis
The doctor will ask about symptoms and past health. The person will be asked about the activities they do. A physical exam will be done. It will focus on the lower leg. This is often enough to diagnose achilles tendinopathy.
If the diagnosis is unclear, images may be taken. This can be done with:
Treatment
Treatment depends on the tendon and how badly it is damaged. Options are:
- Supportive care with rest and ice
- Ankle taping to support the tendon
- Shoe inserts
- Medicines to ease pain and swelling
- Physical therapy
- Extracorporeal shockwave therapy (ESWT) to stimulate healing
Some people may need surgery when other methods do not help.
Prevention
Achilles tendinopathy may be prevented by:
- Wearing proper footwear
- Slowly increasing activities
- Stretching and strengthening the calf muscles
