Achilles tendonitis is a common overuse injury that affects the Achilles tendon, the strongest tendon in the body. The pain often arises in connection with increased training volume but can also develop with prolonged everyday strain.
What is Achilles Tendonitis?
Achilles tendonitis is a condition where the Achilles tendon becomes irritated and overloaded. The Achilles tendon connects the calf muscles to the heel bone and is crucial for movements such as walking, running, and jumping.
When the load on the tendon becomes greater than what the tissue can handle, small micro-injuries can occur. This leads to pain, stiffness, and sometimes swelling in the area. The problems usually arise in the middle of the tendon but can also be located at the insertion point near the heel bone.
Physiotherapist's tips for Achilles Tendonitis
"For Achilles tendonitis, I recommend starting with a heel lift to reduce the strain on the Achilles tendon immediately. Combine with an Achilles tendon support for compression and support during activity. For more severe problems or the need for extra stability, a more advanced ankle brace can provide further relief."

Symptoms
- Local pain and tenderness along the Achilles tendon
- Stiffness and start-up problems, especially in the morning
- Swelling around the tendon, sometimes with redness and warmth
- Pain that increases with exertion
- Creaking sensation or sound with movement
- Resting pain with prolonged inflammation
Symptoms of Achilles tendonitis often arise when the Achilles tendon is repeatedly stressed.
When does Achilles tendonitis hurt the most?
Pain from Achilles tendonitis often arises when the Achilles tendon is heavily or repeatedly stressed.
When taking the first steps in the morning
Many people experience stiffness and pain in the Achilles tendon when they start walking after a night's rest.
When running or jumping
Activities where the calf muscles work intensely can worsen the symptoms.
After physical activity
The pain may be more noticeable after exercise than during the activity itself.
When pressure is applied to the Achilles tendon
Some people experience tenderness when pressing along the tendon or when shoes rub against the area.
Common causes & risk factors
The most common cause of Achilles tendonitis is overuse. This can occur with a rapid increase in training volume, intense activity, or insufficient recovery.
Anatomical factors can also contribute. Overpronation in the foot causes the Achilles tendon to be stressed sideways, which can increase irritation. Inappropriate shoes, hard surfaces, and stiff calf muscles can also increase the risk.
When should you seek medical care?
If you experience persistent pain, difficulty bearing weight on the foot, or if the symptoms do not improve despite rest and reduced activity, medical care should be sought. It is especially important to get an assessment for long-term or recurring problems.
Recommended protection & support
For Achilles tendonitis, the right protection and support can help reduce pain and increase comfort in daily life and activity.
An Achilles tendon protector combines the relief of a heel wedge with compression, which can reduce swelling and provide support to the tendon. A pronation insole can help correct the foot's load and reduce side stress on the Achilles tendon. An Achilles heel wedge can also provide relief by reducing the tendon's range of motion.
Rehabilitation with individually adapted exercises from a physiotherapist is often an important part of the treatment as it strengthens the tendon and improves load capacity.
