Going downstairs can reveal ankle problems that are not obvious during ordinary walking.
As you lower your body onto each step, the shin needs to move forward over the foot while the ankle and lower-leg muscles control the descent.
Quick Answer
Ankle pain when going downstairs can be caused by reduced ankle mobility, a previous ankle sprain, ankle osteoarthritis, tendon problems, anterior ankle impingement, reduced calf strength, or chronic ankle instability. Going downstairs places different demands on the ankle than walking on level ground, so symptoms may appear during stair descent even when normal walking feels comfortable. A physiotherapist can assess ankle mobility, strength, balance, movement control, and load tolerance to identify musculoskeletal factors that may be contributing.
If ankle mobility, strength, joint tolerance, balance, or movement coordination is reduced, this task may become painful.
The location of the pain matters too.
Pain at the front, back, inside, or outside of the ankle can point toward different possibilities, although the location alone cannot establish a diagnosis.
Key Takeaways
- Going downstairs requires controlled ankle movement and weight acceptance, which can expose problems that are not obvious during level walking.
- Limited ankle dorsiflexion can affect how the lower limb moves during stair descent.
- A previous ankle sprain may leave changes in mobility, strength, balance, or movement coordination.
- Achilles, peroneal, and other tendon problems can contribute to ankle pain during weight-bearing activities.
- Ankle osteoarthritis and anterior ankle impingement are possible causes of pain during certain ankle movements.
- Physiotherapy can assess mobility, strength, balance, movement control, and load tolerance when the problem is appropriate for rehabilitation.
- Severe pain, significant swelling, deformity, inability to bear weight, or other concerning symptoms require medical assessment.
Why Does My Ankle Hurt When Going Downstairs?
Going downstairs places the ankle through a controlled weight-bearing movement that is different from walking on level ground.
Ankle dorsiflexion is particularly important because the lower leg needs to progress forward over the foot during the step.
A 2026 study found that people with limited ankle dorsiflexion showed altered lower-limb and pelvic movement during step descent, highlighting why ankle mobility can matter during this task (Rodrigues et al., 2026).
However, reduced mobility is only one possible explanation.
Previous injuries, joint changes, tendon problems, or reduced movement control can also make stairs uncomfortable.
1. Reduced Ankle Dorsiflexion
If your ankle does not move forward easily over your foot, going downstairs may feel restricted or uncomfortable.
You might notice this as pain at the front of the ankle, a feeling of stiffness, or a tendency to compensate through the foot, knee, or hip.
A physiotherapist can compare ankle movement between both sides and assess whether the limitation actually affects functional tasks such as squatting, walking, and stair descent.
2. Previous Ankle Sprain
An old ankle sprain can remain relevant even after the initial swelling and pain have disappeared.
Some people develop ongoing changes in ankle stability, balance, strength, or movement coordination after an ankle injury.
These problems may become more obvious during activities that require greater control, including descending stairs.
The 2021 clinical practice guideline on lateral ankle sprains and chronic ankle instability emphasizes assessment of persistent impairments following ankle injury rather than focusing only on the original pain (Martin et al., 2021).
3. Ankle Osteoarthritis
Ankle osteoarthritis can cause pain, stiffness, and reduced movement during weight-bearing activities.
Going downstairs may become uncomfortable because the ankle has to move while supporting body weight.
Ankle osteoarthritis is also frequently associated with previous trauma, particularly fractures and long-standing instability.
Conservative management can include rehabilitation alongside other medical approaches depending on the severity and individual situation (Herrera-Pérez et al., 2022).
4. Achilles Tendon Problems
The Achilles tendon is heavily involved in controlling movement around the ankle.
If the tendon is sensitive to loading, activities involving repeated ankle movement and weight acceptance may reproduce pain around the back of the ankle or just above the heel.
Going downstairs alone cannot diagnose Achilles tendinopathy.
A clinician would also consider symptoms during walking, running, jumping, calf raises, and other loading activities.
The current clinical practice guideline for midportion Achilles tendinopathy includes examination, load management, and physical therapy interventions as part of evidence-based management (Chimenti et al., 2024).
5. Anterior Ankle Impingement
Pain at the front of the ankle during stair descent can sometimes be associated with anterior ankle impingement.
This condition can produce pain when the ankle moves into dorsiflexion and may also be associated with restricted movement or instability.
Stair climbing and other activities requiring substantial ankle movement can reproduce symptoms in some people.
However, front-of-ankle pain does not automatically mean impingement.
A proper clinical assessment is needed.
6. Peroneal Tendon Problems
The peroneal tendons run along the outer side of the ankle and contribute to foot movement and lateral ankle stability.
Problems involving these tendons can cause pain around the outer or posterolateral ankle and may sometimes be difficult to distinguish from symptoms following a lateral ankle sprain.
If stair descent repeatedly produces pain on the outside of the ankle, tendon and ligament function may both need to be considered (Davda et al., 2017).
7. Reduced Calf Strength or Endurance
The calf muscles help control ankle movement during weight-bearing activities.
If calf strength or endurance is reduced, descending stairs may feel less controlled.
Some people describe this as pain, weakness, trembling, or difficulty controlling the lowering phase.
This can occur after an injury, a period of reduced activity, or prolonged avoidance of loading.
The important point is that weakness should be assessed rather than assumed. Not every painful staircase movement requires strengthening.
8. Chronic Ankle Instability
Do you feel as though your ankle is unreliable when stepping down?
Repeated ankle sprains can sometimes be followed by chronic ankle instability, where a person experiences recurrent giving-way sensations or difficulty controlling the ankle.
Exercise-based rehabilitation can improve function and balance in people with chronic ankle instability.
Recent evidence supports individualized program involving components such as strengthening, balance training, and other targeted exercise approaches (Xu et al., 2026).
Where Does Your Ankle Hurt When Going Downstairs?
The location of your symptoms can provide a useful clue, but it should not be used as a diagnosis by itself.
Pain at the Front of the Ankle
This may be related to restricted dorsiflexion, joint irritation, or anterior impingement.
It may become particularly noticeable when the knee moves forward over the foot.
Pain at the Back of the Ankle
Pain behind the ankle can involve the Achilles tendon or other structures around the rear of the ankle.
The relationship between pain and activities such as running, jumping, or calf raises can provide additional information.
Pain on the Outside of the Ankle
Outer ankle pain can occur after previous sprains or with peroneal tendon problems.
A feeling of instability or repeated giving way is another useful symptom to mention during assessment.
Pain on the Inside of the Ankle
Pain on the inside of the ankle can have several possible causes involving tendons, joints, ligaments, or the surrounding foot structures.
A physiotherapist should assess the whole foot and ankle rather than assuming the painful area identifies one specific structure.
Why Does My Ankle Hurt Going Downstairs but Not Upstairs?
Going upstairs and downstairs are different tasks.
Stair descent requires controlled lowering of the body and places the ankle through a different movement pattern than stair ascent.
Therefore, pain during descent but not ascent is useful information for a clinician.
It may suggest that a particular range of movement, loading phase, or movement-control demand is provoking symptoms.
It does not automatically mean that the ankle is damaged.
Why Does My Ankle Hurt Going Downstairs but Not Walking?
Walking on level ground may not reproduce the same combination of ankle movement, load, and balance demands as stair descent.
This is why someone can walk relatively comfortably but experience pain when going downstairs.
The difference can actually help during a physiotherapy assessment because the clinician can compare how the ankle behaves during walking, squatting, stepping down, and other functional movements.
Why Does My Ankle Hurt Going Downstairs After an Old Injury?
If the symptoms started after an old ankle injury, the injury history becomes particularly relevant.
A previous sprain or fracture may have affected mobility, strength, balance, or confidence in the ankle.
This does not mean the old injury is necessarily the direct cause of today’s pain.
Instead, it provides an important piece of the clinical history.
Can Tight Calves Cause Ankle Pain Going Downstairs?
A tight-feeling calf can be associated with restricted ankle dorsiflexion, but the sensation of tightness does not automatically mean that the calf muscle is the problem.
Ankle mobility can be influenced by several factors, including joint movement, muscle-tendon flexibility, previous injury, pain, and the way the movement is performed.
Rather than repeatedly stretching the calf, it is more useful to determine why the ankle is not moving comfortably.
Can Body Weight Make Stair Descent Harder?
Body weight is one factor that influences the mechanical demands placed on the lower limb during weight-bearing activities.
However, ankle pain should not automatically be attributed to body weight.
Previous injury, joint health, muscle capacity, movement strategy, activity level, and other factors can all contribute.
A good physiotherapy assessment focuses on modifiable movement and load-related factors rather than reducing the problem to weight alone.
What Can You Do If Your Ankle Hurts Going Downstairs?
If the pain is mild and you can walk safely, you can temporarily reduce unnecessary stair repetitions and avoid repeatedly testing the painful movement.
Using a handrail may improve confidence and control.
Do not repeatedly force the ankle into a painful range simply to see whether it has improved.
If symptoms are persistent, progressively worsening, or interfering with normal activities, professional assessment is more useful than continuing to self-test the joint.
Can Ankle Exercises Help?
They can, but the right exercise depends on the reason for the pain.
Someone with chronic ankle instability may benefit from progressive strengthening and balance work.
Someone with restricted mobility may need a different rehabilitation approach.
Someone with significant joint irritation may require medical assessment before progressing exercise.
Exercise should therefore be matched to the person’s impairments and functional goals rather than selected from a generic list of ankle exercises.
What Does a Physiotherapist Check?
A physiotherapist may assess:
- Ankle dorsiflexion and other movements
- Calf strength and endurance
- Foot and ankle control
- Balance and stability
- Walking pattern
- Squatting and step-down movement
- Previous ankle injuries
- Swelling and symptom behaviour
- Recent changes in activity
- Tolerance to different loads
The step-down task can be particularly useful because it allows the clinician to observe how the ankle, knee, hip, and trunk work together.
How Can Physiotherapy Help?
If the problem is musculoskeletal and appropriate for physiotherapy, treatment may include progressive strengthening, mobility work, balance training, movement retraining, activity modification, and gradual return to more demanding activities.
For chronic ankle instability, recent evidence supports exercise-based rehabilitation for improving patient-reported function, although the certainty and response can vary between individuals.
Physiotherapy should not be presented as a treatment for every cause of ankle pain.
Suspected fracture, significant joint pathology, infection, acute severe injury, or other conditions requiring medical investigation may need medical assessment first.
When Is Physiotherapy Not the First Step?
Physiotherapy is not always the appropriate first step.
Medical assessment is important if ankle pain follows a significant injury, you cannot bear weight normally, there is obvious deformity, or there is substantial swelling.
A hot, red, markedly swollen joint, particularly with fever or feeling unwell, also requires medical attention rather than being treated as a routine movement problem.
When Should You See a Doctor?
Seek medical assessment if:
- You cannot bear weight normally
- The ankle looks deformed
- There is severe or rapidly increasing swelling
- Pain started after significant trauma
- The joint becomes hot, red, or markedly swollen
- You have fever or feel systemically unwell
- Pain continues to worsen despite reducing aggravating activity
- Symptoms persist without a clear improvement pattern
These features may require investigation beyond a routine physiotherapy assessment.
Myth vs Fact
Myth: If my ankle hurts going downstairs, I must have damaged the joint.
Fact: Stair descent places different demands on ankle movement and load control. Pain can be related to mobility, strength, tendon sensitivity, previous injury, movement coordination, or joint changes. Pain alone does not confirm structural damage.
Myth: If I can walk normally, there cannot be anything wrong with my ankle.
Fact: Different activities place different demands on the ankle. A person may walk comfortably on level ground but experience pain during stair descent.
Myth: Stretching the calf will always fix ankle pain on stairs.
Fact: Calf tightness is only one possible contributor. The ankle may also be affected by joint mobility, previous injury, tendon problems, weakness, or movement-control deficits.
Myth: You should completely avoid stairs until the ankle pain disappears.
Fact: Complete avoidance is not always necessary for mild symptoms, but repeatedly forcing a painful movement is also not advisable. Activity should be adjusted according to symptoms and safety.
Lesser-Known Fact: Going Downstairs Can Expose a Mobility Problem
Someone can have enough ankle movement for ordinary walking but still struggle with tasks requiring greater controlled movement.
That is why stair descent can sometimes reveal a limitation that is not obvious during a basic walking assessment.
The important question is not simply, “Does the ankle hurt on stairs?” It is also, “What changes when the ankle is asked to control this particular movement?”
That distinction is one reason functional assessment is valuable in physiotherapy.
Final Thoughts
Ankle pain when going downstairs is a movement-related symptom rather than a diagnosis. Reduced ankle mobility, previous injuries, tendon problems, arthritis, weakness, and changes in movement control can all contribute. Paying attention to where the pain occurs, when it appears, and whether the ankle feels stiff or unstable can provide useful information. If the problem keeps returning or interferes with everyday activities, an appropriate physiotherapy or medical assessment can help determine the next step.
Conclusion
Ankle pain when going downstairs can have several possible explanations, including reduced dorsiflexion, a previous ankle sprain, ankle osteoarthritis, Achilles or peroneal tendon problems, anterior ankle impingement, reduced calf capacity, or chronic ankle instability.
The exact cause cannot be determined from stair pain alone.
Pay attention to where the pain occurs, whether the ankle feels stiff or unstable, whether symptoms appear during walking or exercise, and whether there has been a previous injury.
If the pain keeps returning or affects everyday activities, a physiotherapy assessment can help identify relevant mobility, strength, balance, movement-control, and load-tolerance factors.
When symptoms suggest a more serious injury or medical condition, medical assessment should take priority.
Frequently Asked Questions
1. Why does my ankle hurt when going downstairs?
Possible causes include reduced ankle mobility, a previous ankle sprain, ankle osteoarthritis, tendon problems, anterior ankle impingement, reduced calf strength, and chronic ankle instability. The exact cause depends on the individual’s symptoms and examination findings.
2. Why does my ankle hurt going downstairs but not upstairs?
Going downstairs involves controlled lowering of the body and places different demands on ankle movement and load control than going upstairs. This can expose limitations that are not obvious during stair ascent.
3. Why does my ankle hurt going downstairs but not walking?
Level walking and stair descent require different combinations of ankle movement, balance, and load control. A person may therefore experience pain on stairs while walking comfortably on flat ground.
4. Can an old ankle sprain cause pain when going downstairs?
Yes. Some people experience persistent changes in ankle mobility, strength, balance, stability, or movement coordination after an ankle sprain. These changes can become noticeable during more demanding tasks such as stair descent.
5. Can tight calf muscles cause ankle pain going downstairs?
A tight-feeling calf can be associated with limited ankle movement, but calf tightness is not always the underlying cause. Joint mobility, previous injury, pain, tendon problems, and movement patterns can also affect ankle movement.
6. Can ankle exercises help with pain when going downstairs?
Exercises may help when the problem involves reduced strength, balance, mobility, or movement control. The appropriate exercises depend on the individual’s assessment and should be progressed according to symptoms and functional goals.
7. Can physiotherapy help ankle pain when going downstairs?
Physiotherapy may help when musculoskeletal factors such as restricted mobility, weakness, balance deficits, movement-control problems, or reduced load tolerance contribute to the symptoms. Treatment should be based on an individual assessment.
8. When should I see a doctor for ankle pain on stairs?
Seek medical assessment for severe or worsening pain, significant swelling, inability to bear weight, deformity, pain after major trauma, or an ankle that becomes hot, red, or markedly swollen. Fever or feeling unwell alongside joint symptoms also requires medical attention.
