All about Achilles tendon problems: causes, symptoms, and what you can do about them

What are Achilles tendon complaints?

The Achilles tendon connects the calf muscles to the heel bone and endures significant stress with every step. When running, jumping, or accelerating, the tendon absorbs great forces. When the load exceeds the tendon's capacity, irritation and pain can occur.

Complaints often develop gradually. Many athletes first notice some stiffness or sensitivity after a training session, after which the complaints slowly increase. A rapid increase in training intensity, a lot of hill training, stiff calf muscles, or worn-out shoes can play a role in this.

How do Achilles tendon complaints feel?

Achilles tendon complaints often cause a pulling, burning, or stiff sensation just above the heel. Especially the first steps in the morning or at the start of a training session often feel painful or stiff. During movement, the tendon sometimes seems to loosen up a bit, but afterward, the complaints often return.

Additionally, the tendon can be sensitive to touch and sometimes feel slightly thickened or swollen. Many athletes also notice that sprinting, climbing stairs, or explosive movements worsen the complaints.

When should you be concerned?

If the complaints persist longer or worsen, it is advisable to consult a physiotherapist or doctor. Especially when the pain arises suddenly, you've felt a snapping sensation, or you have difficulty walking or pushing off, it is important to take the complaints seriously.

A partial or complete tear of the Achilles tendon requires medical assessment.

How does Achilles tendon overuse occur?

The Achilles tendon recovers relatively slowly. As a result, minor irritations can accumulate when load and recovery are not well balanced. This is often seen in athletes who suddenly increase their mileage, train faster, or start intensely again immediately after a rest period.

Also stiff calves often play an important role. The more tension there is on the calf muscles, the greater the pulling force on the Achilles tendon becomes. As a result, complaints can keep returning if only the tendon is treated and the surrounding muscles are not addressed.

When should you see a physical therapist or doctor?

If symptoms persist for weeks or clearly worsen, professional guidance is advisable. It is also important to have the Achilles tendon evaluated in case of swelling, redness, loss of strength, or sudden sharp pain.

Early treatment often prevents symptoms from becoming chronic.
