Understanding Achilles tendon problems and building activity back up

Your heel feels stiff when you get up. Climbing stairs causes a pulling sensation at the back of the lower leg, or the tendon feels more tender the morning after a longer walk. Perhaps you have already taken a break and find that symptoms return when you restart. The question is then not simply whether you should rest, but what level of activity currently suits your tendon.

When pain starts suddenly after a snapping sound

A sudden snapping sound or the feeling of being kicked in the calf, followed by loss of strength, can indicate an Achilles tendon rupture. Seek medical assessment immediately. Being able to take a few steps, or pain easing later, does not reliably rule out a rupture. Until you have been assessed, avoid testing the tendon under load or stretching it forcefully. For a severe injury or another emergency, call 112. Waiting for a routine online appointment is not appropriate for an acute severe injury. The following information mainly concerns longer-standing symptoms and does not replace this urgent assessment.

Understanding

A closer look

Together, we want to establish where your symptoms arise and how to plan a sensible return to your usual activities. Longer-standing tendon problems often require patience. A clear plan is more helpful than switching quickly between complete rest and your previous level of activity.

What the Achilles tendon does

The Achilles tendon connects the calf muscles to the heel bone. It transmits force when we push off the ground while walking, climb stairs or run. In doing so, it has to cope with very different loads. An unfamiliar increase in distance, pace or training may therefore be relevant to your symptoms, although not every case can be traced to a single trigger. The term tendinopathy is often used for persistent tendon pain. It describes a painful tendon problem with a change in the tendon’s ability to tolerate load. This is not simply the same as short-term inflammation. Equally, an abnormal tendon finding does not automatically mean that the tendon has ruptured. These distinctions matter because they influence further treatment.

Further information

Why the precise location matters

Symptoms may be located directly where the tendon attaches to the heel bone or a few centimetres above it. At the attachment, mechanical loading in certain foot positions is one factor. A strong stretch that lowers the heel well below a step may therefore be unhelpful in this area. An exercise programme should account for these differences. The starting position, range of movement and load are adapted to the examination findings and your response. Do not therefore adopt a demanding programme using a step without assessment simply because it was recommended for the Achilles tendon. This website explains the underlying principles; the precise amount and intensity belong in your individual treatment plan.

What we assess together

The location of the pain, when it started and the pattern of activity are important for assessment. We want to know how the tendon behaves during and after an activity. Previous injuries, operations, new medication and other conditions are also part of the discussion. Bring your medication list and do not change an existing treatment solely because of information on a website. The physical examination assesses the tendon in relation to the foot, ankle and function. Ultrasound may add information when there is an appropriate question to answer. Other imaging is used if it is needed to address a relevant unanswered question. The tendon’s appearance and what you can do in daily life are assessed together. Treatment is not guided solely by whether an image looks as normal as possible.

Choosing the right level of activity together

For longer-standing tendinopathy, gradually adapting and rebuilding tendon loading is often a key part of treatment. Complete rest for a long time does not automatically restore the tendon’s capacity. Equally, continuing to train without changes may overload it. We want to agree a level of activity that you understand and can put into practice in daily life. At first, this may mean changing activities that particularly trigger symptoms while continuing those you tolerate better. Targeted calf exercises are selected according to the findings and adjusted gradually. Your feedback matters: how does the tendon feel the next morning? Is the same walking distance becoming easier? Is there a marked deterioration? A rigid plan without this feedback cannot reflect the different ways symptoms develop.

Additional options and their limitations

Footwear, temporarily reducing strain or other aids may be considered where appropriate. They do not, however, automatically replace rebuilding the tendon’s capacity. Whether physiotherapy guidance or another measure would be useful is determined by the findings and progress so far. Shockwave therapy may be discussed as an additional option for selected longer-standing symptoms. The evidence is not the same for every type of Achilles tendon problem. For ACP or PRP, the evidence for the specific form of Achilles tendon problem needs to be considered. It does not allow us to predict faster healing reliably for your individual situation. Before adding a treatment, its aim, alternatives and remaining uncertainty therefore need to be explained. Cortisone injection directly into the Achilles tendon is generally not recommended because it can increase the risk of tendon rupture.

Assessing progress through everyday activities

Progress is often assessed over weeks and months. The diagnosis alone cannot establish a fixed recovery time. A specific goal helps, such as being able to walk a certain distance again or use stairs more confidently. One good exercise session does not yet mean that you can tolerate every previous activity again. If progress does not follow the expected course, the assessment should be reviewed. This is particularly important if there is marked new weakness, a sudden change or worsening symptoms. If significant limitations remain despite appropriate non-surgical measures, further specialist assessment may be useful. This does not automatically mean surgery.

Frequently asked questions

Do I need to stop all activity if I have Achilles tendon problems?
Not in every situation. We first need to establish whether there is an acute injury. For longer-standing symptoms, activity is often adapted and built up gradually. What you can continue doing depends on the findings and how you respond.
Is strong stretching always helpful?
No. Strong stretching can be unhelpful, particularly when symptoms are right at the tendon attachment. Exercises should suit the affected area. You do not need to force a painful movement for an exercise to be effective.
Does a thickened tendon mean it has ruptured?
Not automatically. Thickening, pain and loss of function need to be assessed together. A sudden event with loss of strength requires a different level of urgency from symptoms that have developed gradually over several months.
Does health insurance cover additional treatments?
We first discuss what an additional treatment could aim to achieve for you, its limitations and the alternatives. If your German statutory health insurer does not cover the treatment being considered, we explain self-funding. You can take time to decide after the discussion. Before the treatment, you receive an estimate and confirm your wish to proceed and your agreement to pay by signing.
