Posterior Shin Splints
Posterior Shin Splints
Inner shin pain guidance for runners, field-sport athletes and active people.
Does this pattern fit your shin pain?
Symptoms vary, but these clues commonly occur with an MTSS-type presentation. They do not confirm a diagnosis.
Location
Pain and tenderness usually sit along the lower inner border of the tibia.
Spread
Tenderness is often diffuse rather than limited to one small, exact spot.
Trigger
Running, jumping, hills, speed work and harder surfaces may provoke symptoms.
Timing
Pain may build during activity, ease when load stops and return later or the next morning.
Training change
A recent jump in distance, pace, hills, frequency or sport load is common.
Progression
Symptoms may start earlier and take longer to settle if the same impact load continues.
What are posterior shin splints?
Posterior shin splints is a common but informal label for exercise-related pain along the posteromedial, or inner-back, border of the tibia. In practice, it often overlaps with medial tibial stress syndrome.
MTSS is better understood as a tibial loading problem than as inflammation of one muscle attachment. Repeated impact can exceed the lower leg’s current capacity to adapt. The bone and nearby tissues may all contribute to pain. This is why treatment usually addresses training load, calf and foot capacity, movement, recovery and footwear together.
The condition belongs within a broader shin pain group. Related problems include general shin splints, anterior shin splints and tibial stress fracture.
What else can cause inner shin pain?
Location is useful, but it is not enough to diagnose the cause. A clinician may consider these patterns during assessment.
Medial tibial stress syndrome
Pain is typically spread along the inner tibial border and linked with running or jumping load. Tenderness across at least 5 cm supports this pattern but does not prove it.
Tibial bone stress injury
Concern rises when pain is sharply localised, progresses quickly, occurs with walking or rest, or persists despite reducing load. Prompt assessment matters because early X-rays can be normal.
Other lower-leg conditions
Exertional compartment syndrome can cause tightness, cramping or altered sensation during exercise. Posterior tibial tendon pain is often felt nearer the inner ankle or arch.
Why do posterior shin splints develop?
There is rarely one cause. Symptoms usually appear when repeated tibial load increases faster than the body can adapt. The relevant mix differs from person to person.
- Training load: sudden changes in distance, pace, hills, frequency, jumping or playing time.
- Recovery: too little recovery between hard sessions, reduced sleep or returning too quickly after a break.
- Physical capacity: calf fatigue, reduced ankle movement or limited foot, hip and trunk control.
- Running environment: abrupt changes in shoes, terrain or surface.
- Individual health: previous bone stress injury, low energy availability and other bone-health factors can change clinical concern.
Foot posture can be one contributor, but it should not be treated as a diagnosis. A biomechanical assessment can help identify which factors are relevant and which are not.
Who gets posterior shin splints?
MTSS-type pain is common in people exposed to repeated impact, especially when their workload changes. This includes distance runners, sprinters, field-sport athletes, dancers and military recruits. It also affects people starting a running program or returning after illness, injury or a training break.
Experienced athletes are not immune. A familiar weekly distance can become a new stress when pace, hills, surface, recovery or other training changes at the same time. See the running injuries guide for broader load-management advice.
How are posterior shin splints assessed?
Your physiotherapist will ask when the pain started, how it behaves during and after activity, and what changed in your training. They will map tenderness along the tibia and assess walking, calf loading, ankle movement, foot function and relevant hip or trunk control. A running review may be useful when symptoms allow.
Imaging is often unnecessary when the history and examination clearly fit MTSS. Medical review or imaging may be appropriate when pain is focal, occurs with walking or rest, is worsening, or the diagnosis remains uncertain. MRI is commonly used when a tibial bone stress injury needs to be assessed; an early X-ray may not show it.
A hop test is not a self-diagnosis tool. Clinicians may avoid impact testing when the history already raises concern for a bone stress injury.
How are posterior shin splints treated?
Treatment aims to calm the current irritation, restore capacity and rebuild impact gradually. Complete rest is not always needed, but continuing the same painful training load can delay recovery.
-
Adjust impact load
Reduce or pause the running, jumping, hills or speed work that aggravates symptoms. Maintain fitness with comfortable lower-impact exercise where appropriate.
-
Restore comfortable movement
Address relevant ankle or calf restriction without repeatedly provoking the shin. Treatment should match examination findings rather than use a routine stretch for everyone.
-
Build lower-leg capacity
Progress calf, soleus and foot strength, then add single-leg and impact work as symptoms permit. Hip and trunk exercises may be included when they address an identified need.
-
Review contributing factors
Check training progression, recovery, footwear, surface and running mechanics. Orthotics may help selected people, but they are not a stand-alone cure.
-
Return to running gradually
Begin with a manageable walk-run dose. Build duration or distance before adding pace, hills, repeated days and harder surfaces.
A tailored sports physiotherapy plan can adapt these stages to your symptoms, sport and starting capacity.
Can you run with posterior shin splints?
Sometimes, but the decision should follow symptom behaviour rather than a fixed pain score. Running is more reasonable when symptoms remain mild, your gait stays normal and the shin settles without a worse response later that day or the next morning.
Reduce
Shorten the run or lower the pace if symptoms build but settle promptly and do not alter your movement.
Cross-train
Use comfortable lower-impact exercise when pain starts earlier, lasts longer or is worse the next morning.
Stop and assess
Stop impact and arrange review if pain is sharp or focal, changes your gait, hurts with walking or continues to worsen.
Before increasing running, aim for comfortable walking, improving tibial tenderness and good tolerance of the rehabilitation loads chosen for you. Start below your previous training level and change one major variable at a time.
How long do posterior shin splints take to settle?
Recovery commonly takes several weeks and may take longer. The timeline depends on symptom severity, how early load is adjusted, training history, rehabilitation consistency and whether a bone stress injury is present. A fixed four-to-eight-week promise is not reliable for every person.
Progress is usually judged by improving daily comfort, less tenderness, better tolerance of calf and impact loading, and a stable response to gradually increased running. Flare-ups often mean the latest increase was too large, not that all activity must restart from zero.
How can you reduce the chance of recurrence?
- Build running or jumping load progressively, especially after a break.
- Avoid increasing distance, pace, hills and training frequency at the same time.
- Keep calf and foot strength work in your weekly program.
- Allow enough recovery between demanding impact sessions.
- Replace worn footwear and introduce major shoe or surface changes gradually.
- Respond early if inner-shin symptoms begin to build again.
Research supports a multifactorial approach. Neuromuscular programs and overpronation-control insoles have reduced MTSS incidence in some studied groups, but prevention should still be matched to the individual rather than prescribed from one risk factor.
What does recent research mean for rehabilitation?
A 2025 randomised study found benefit from adding lower-leg exercises to a multimodal program for recreational runners with MTSS. This supports progressive strengthening, but it does not establish one universal exercise recipe. A 2020 systematic review also found that the evidence for many commonly used treatments remained limited or inconsistent.
Current bone-stress guidance supports considering training load, recovery and bone health when symptoms suggest a stress injury. The NCBI medical overview of medial tibial stress syndrome provides a broader clinical summary.

Posterior shin splints FAQs
What are posterior shin splints?
Posterior shin splints is an informal name for exercise-related pain along the inner-back border of the shin. It commonly overlaps with medial tibial stress syndrome, a tibial loading problem involving bone and nearby tissues.
Is posterior shin splints the same as medial tibial stress syndrome?
The terms are often used for the same inner-shin pain pattern, although posterior shin splints is less precise. A clinician should still assess other causes, particularly when pain is focal, severe or present with walking or rest.
How long do posterior shin splints take to settle?
Recovery commonly takes several weeks and can take longer. Timing depends on symptom severity, training history, how early load is adjusted, rehabilitation consistency and whether a bone stress injury is present.
Can you keep running with posterior shin pain?
Some people can continue with a reduced dose when symptoms remain mild, gait stays normal and pain is not worse later or the next morning. Stop impact and seek assessment if pain becomes sharp, focal, progressive or painful with walking.
When should you worry about a tibial stress fracture?
Arrange prompt assessment for one very tender spot, pain with normal walking, rest or night pain, swelling, or symptoms that continue to worsen despite reducing impact. Early X-rays can be normal, so clinical review matters.
Do orthotics help posterior shin splints?
Orthotics may help selected people when foot mechanics or load distribution are relevant. They work best as one part of a broader plan that addresses training load, lower-leg capacity, footwear and recovery.
