Shin Splints
Shin splints, or medial tibial stress syndrome, is pain spread along the inner edge of the shin bone. It often follows an increase in running or jumping, and bone stress may contribute. Pain focused on one spot, pain at rest or a limp needs assessment for a possible bone stress injury.
Key points

- Calf and hip strengthening, and a running plan cut back and then rebuilt.
- What you can do now
- Cut back running, keep fit another way. Strengthen your calves.
- How long it takes
- Many runners return over several weeks with a structured plan.
- When to see a doctor first
- Some signs need emergency care. Check the list before you start treatment.
Symptoms
Does this sound like you?
- Pain along the inner edge of the shin bone
- Pain with running or jumping
- Tenderness along the shin bone (tibia)
- Pain at start of exercise
- Worse with increased activity
Often alongside it
- Calf tightness
- Foot fatigue
- Running differently to protect the shin
- Morning discomfort
- Swelling over shin
It comes on gradually after an increase in training. At first the pain comes after activity; as it progresses, it comes during activity too.Book an assessment for shin splints
When to see a doctor first
Go to emergency
A tight, very painful lower leg after an injury or a hard session, pain out of proportion to what happened, or numbness and weakness in the foot
Go to emergency now to rule out acute compartment syndrome
A foot that suddenly becomes unusually cold, pale, or blue, or a toe with a new colour change that persists, especially with pain, numbness, or weakness
Go to emergency now; the blood supply may be blocked
Check with your doctor
Pain at one small spot on the shin bone, pain at night or at rest, or pain that changes the way you walk
Stop running and other impact activity and see your family doctor before starting physiotherapy, to check for a stress fracture. Do not hop or exercise to exhaustion to test it
Pain on the front of the shin rather than the inner edge, especially a tender spot on the bone
Stop impact activity and see your family doctor promptly; stress fractures on the front of the shin heal poorly and need medical review
Tightness, numbness, or foot slapping that comes on at the same point in every run and settles within minutes of stopping
See your family doctor, who can refer you for testing for exertional compartment syndrome
A familiar, brief colour change in the toes triggered by cold, already diagnosed as Raynaud's
Follow your existing care plan. New, persistent or unusually severe changes need medical assessment, and the emergency signs above still apply. Do not assume an unexplained change is Raynaud's
Colour or feeling changes in the foot that come on only during exercise and fully settle with rest
Stop that activity and arrange a prompt medical assessment of the circulation to the leg
Treatment
How it is treated
Main approach. Calf and hip strengthening that builds up step by step, a running plan that is cut back and then rebuilt, and for some runners a change in step rate or a cue to land more softly, can support a gradual return to running over several weeks.
Alongside it. Changing your training and doing other exercise such as cycling or pool running (cross-training) keep up your fitness while the bone adapts, and reduce the repeated load on the shin bone (tibia).
Managing it over time. Building up training gradually and changing how you run may help lower the risk of it coming back, though the evidence for preventing shin splints (medial tibial stress syndrome) is limited.
A typical rehabilitation progression
Three phases, from settling symptoms to returning to full activity.
Recovery from shin splints is usually staged: calm the symptoms first, then rebuild the strength and capacity of the area, then return to your full activities. The phases below show how that can progress.
Phase 1Cutting Back and Starting to Load (Weeks 1 to 3)
Bring down the tenderness along the shin bone and the pain with activity, while keeping up your fitness and starting to rebuild calf strength. Running is often reduced or paused for a short period, and the return to running is based on checks I do in clinic, such as no tenderness along the shin bone and comfortable single-leg hopping, rather than on hopping tests at home. Other exercise (cross-training) keeps up your fitness. Research by Winters and colleagues on diagnosing shin splints, including pressing along the shin bone and hop testing in the clinic, guides both the assessment and decisions about returning to running.
Example exercises
- Double-leg calf raises on flat ground, 3 sets of 15, 3 seconds up and 3 seconds down
- Seated heel raises with the knee bent, for the lower calf muscle (soleus), 3 sets of 15
- Short-foot holds (gently raising the arch without curling the toes) and other drills for the small muscles inside the foot, 2 to 3 sets of 10 holds
- Cycling, pool running, elliptical or rowing to keep up your fitness, at an easy pace where you could still hold a conversation
- Strengthening for the muscles on the side of the hip and the main buttock muscle (hip and gluteus maximus), such as side planks and single-leg bridges, 3 sets of 10 to 12
Possible progression milestones
Possible milestones, adapted to the person rather than treated as fixed cut-offs: the shin bone no longer tender to press, comfortable single-leg hopping, and double-leg calf raises tolerated without shin pain the next morning.
Phase 2Building Load and Returning to Running (Weeks 3 to 8)
Rebuild calf, hip and running strength while bringing running back in planned walk-run intervals. Running form is checked, and for some runners a small change from their usual step rate, or a cue to take shorter steps or land more softly, is tried, based on how they run and how the shin responds. Weekly running volume increases in small steps, and sessions are spaced out to let the bone recover.
Example exercises
- Single-leg calf raises, 3 sets of 8 to 15, progressing to loaded calf raises as tolerated
- Seated calf raises with added weight, for the lower calf muscle (soleus), 3 sets of 8 to 12
- Step-ups and split squats, 3 sets of 8 to 10 per side, to build single-leg strength
- Walk-run intervals starting at 1 minute run and 2 minutes walk, progressing toward continuous running on soft surfaces
- If it suits your running pattern, a small step-rate change from your usual cadence or a softer-landing cue, practised in short blocks within easy runs
Possible progression milestones
Possible milestones, adapted to the person rather than treated as fixed cut-offs: a continuous easy run on a soft surface without shin pain during or the next day, a solid set of single-leg calf raises on the affected side, and load progressing over several weeks without symptoms rising.
Phase 3Full Training and Prevention (Weeks 8+)
Return to normal training volume, bring back speed, hills and harder surfaces, and build the habits that keep the load on the shin bone within what it can handle. The aim is not just for the pain to go, but for you to take on the next training block without slipping back. Watching weekly increases in training, continuing calf and hip strength work, and sticking to planned easier weeks are the main prevention tools I use, although the evidence for preventing shin splints is limited.
Example exercises
- Hopping drills (), progressing from small, springy two-leg hops (pogo hops) to single-leg hops in place and for distance, 3 sets of 10 to 20 hops
- Tempo and interval running brought back as one harder session per week, gradually building volume
- Hills reintroduced after 2 to 3 weeks of consistent flat running, starting with gentle gradients
- Continued heavy calf raises, 3 sets of 6 to 12 with load, twice weekly
- Training log with weekly volume, surface, and symptom notes to catch future load errors early
Possible progression milestones
Return to pre-injury weekly mileage and intensity without shin pain, single-leg hopping tolerated equally on both sides, and at least 4 weeks in a row of training without symptoms, including at least one harder session per week.
What you can do now
- Cut back running, keep fit another way. Reduce or pause running for now, and keep your fitness with cycling, pool running, an elliptical or rowing, at a pace where you could still hold a conversation. This keeps the return to running from starting at zero.If the pain is at one small spot on the bone, comes at night or at rest, or changes the way you walk, stop running and other impact activity and see your family doctor before starting physiotherapy, to check for a stress fracture.
- Strengthen your calves. Start with slow calf raises on both feet on flat ground, 3 sets of 15 (3 seconds up, 3 seconds down), and seated heel raises with the knee bent, 3 sets of 15. Stronger calf muscles help share the load with the shin bone.If the shin hurts the next morning after calf raises, ease back.
- Add hip and buttock strength work. Side planks and single-leg bridges, 3 sets of 10 to 12, build the muscles on the side of the hip and the buttock. Strength work for the calves, buttocks and trunk carries on while you cross-train.
- Do not test it by hopping. Avoid hopping over and over or exercising to exhaustion to see whether the shin still hurts. The checks for a return to running, such as no tenderness along the bone and comfortable single-leg hopping, are done in the clinic.
- Rebuild running in small steps. When running returns, start with walk-run intervals, such as 1 minute of running and 2 minutes of walking, on soft surfaces. Increase weekly volume in small steps with regular easier weeks, because bone adapts more slowly than muscle.Do not run through pain that climbs from week to week, a shin that is tender after sessions, or pain narrowing to one spot; pain at one spot needs the stress fracture check in the warning signs on this page.
What I use in clinic
- Running technique changes (gait retraining). In a small study of runners, cues to land more softly reduced the impact shock through the shin bone (Crowell and Davis, 2011).
- Gradually increasing exercise load. Builds how much load the bone and soft tissues can tolerate.
Recovery
How long it takes
Many runners return to running over several weeks with a structured plan. The timeline depends on how long symptoms have been building and how training load is managed.
If training keeps increasing despite worsening pain, bone stress can progress to a stress fracture.
What changes the timeline
- Training errors, such as building up distance or speed too quickly
- How your feet and legs move when you run (biomechanical factors)
- Bone health
- Footwear
How I track it. I track how much the pain gets in the way of the tasks that matter to you, how well you move when I test those tasks in clinic, and how confident you feel in daily activities
Similar conditions
Conditions that can feel similar
- Tibial Stress Fracture
- Pain gathers at one spot on the shin bone rather than spreading along a stretch of 5 cm or more. Hopping on that leg, or single-leg calf raises until the calf gives out, typically brings on sharp pain in that one spot and often cannot be finished. Pain at night or at rest points far more to a bone stress injury than to shin splints (medial tibial stress syndrome), and this combination warrants imaging before loading progresses.
- Chronic Exertional Compartment Syndrome
- Pain builds during running in a predictable time or distance window, is often described as tightness, squeezing, or a cramping band of pressure, and may come with numbness or the foot slapping down as you run (foot slap). It eases within minutes of stopping rather than worsening afterward. The edge of the shin bone is typically not tender, which is a key difference from shin splints.
- Popliteal Artery Entrapment
- Calf or shin pain brought on by exercise, with a foot that turns cool, changes colour or tires, and that settles quickly with rest. It is more common in younger athletes and can mimic compartment syndrome. Diagnosis comes from checking the blood vessels (vascular assessment), not from loading the muscles and bones.
- Tibialis Posterior or Deep Posterior Compartment Tendinopathy
- Tenderness runs behind the inner ankle bone and up the deep calf, rather than along the edge of the shin bone. Rising onto your toes on one leg brings on the pain, and the heel may not tip inward as it rises. A tired arch is often more noticeable than shin pain.
- Saphenous or Tibial Nerve Irritation
- Burning, tingling or shooting pain along the path of a nerve, rather than a spread-out ache along the edge of the shin bone. Pressing on the area does not reliably find the same tender spot, and symptoms often carry on at rest rather than depending only on activity.
- Lumbar-referred Leg Pain
- Shin symptoms that change with back positions, sitting or bending forward, rather than with running. Back pain, a history of disc or nerve root irritation, and shin symptoms brought on by tests that stretch the nerves (neural tension tests) all point to the lower back rather than the shin itself.
Questions
What patients ask me most
Do I have shin splints or a stress fracture?
Shin splints usually produce diffuse tenderness along a longer stretch of the inner shin bone (roughly 5 cm or more), and pain often eases somewhat with walking or gentle movement. A stress fracture is usually a single focal spot of bone pain, and night pain or rest pain is a red flag. Stop impact activity and get assessed if pain becomes focal over the bone, persists at rest, or changes your walking. Do not repeatedly hop or exercise to exhaustion to test it yourself. When the picture points to a stress fracture, I pause running, and when imaging would change the plan, I flag it to your family doctor or specialist and refer you.
Should I run through shin splints?
Running through rising shin pain raises the risk of the bone stress progressing, so the answer is no when pain is climbing week over week, when the shin is tender after sessions, or when pain is narrowing to one spot. Early and mild cases often tolerate reduced volume and softer surfaces, and for some runners a small change in step rate or a softer-landing cue helps, but this only works if symptoms stabilise or improve. If they do not, a short window away from running with dedicated calf loading often settles things faster than pushing through.
How long do shin splints take to settle?
Mild cases caught early often settle within a few weeks with load reduction and calf strengthening. Cases that have been building for months often need a longer period of progressive rehab, sometimes a few months, before full running volume returns. A big variable is whether the original training spike is actually modified. Without that, symptoms often recur as mileage rebuilds.
Does increasing running cadence help shin splints?
It can help some runners. A small increase from your usual step rate (5 to 10 percent is the range most often studied) shortens the stride and reduces overstriding. The effect on shin loading is less certain: in one small experiment, cues to take shorter steps or to run softly reduced a measure of impact on the shin slightly at an easy pace, while a step-rate increase did not (Anderson et al., Gait & Posture 2024). Impact measures are not the same as the load inside the bone, and none of this proves faster recovery. I choose a cue, if any, based on your running pattern and how your shin responds, alongside calf strengthening and a sensible mileage rebuild.
Are orthotics or new shoes a solution?
They can help, but rarely on their own. Shin splints (medial tibial stress syndrome) are primarily a training-load problem layered on top of how a runner is built and moves (biomechanical predispositions). Footwear changes and orthoses sometimes reduce the load on the inner shin, especially in runners whose feet roll in a lot (overpronation) or whose arches collapse, but they do not build bone or tendon capacity. Most runners do better by pairing any footwear adjustment with a structured strength and load-management plan rather than expecting the shoe to do the work.
Can I cross-train while shin splints heal?
Yes, and I encourage it. Cycling, pool running, elliptical work, and rowing maintain aerobic fitness without the repeated impact through the shin bone that drives shin splints. Strength work for calves, glutes, and trunk continues throughout. This keeps the return to running from starting at zero and reduces the temptation to rush mileage rebuild.
Why did my shin splints come back when I started running again?
Usually because the running volume, speed, or surface returned faster than the bone could adapt. Bone remodels on a slower timeline than muscle, and a tibia that was stressed enough to become painful needs a methodical build-up, with small weekly increases and regular down-weeks. Recurrence usually points to either an unresolved strength deficit or a training plan that outran the tissue.
The science
The Science of Shin Splints
Medial tibial stress syndrome involves periosteal irritation and microtears where muscles attach to the tibia. It represents on a continuum that can progress to without proper management.
Contributing factors
Shin splints typically develop from a combination of training errors and biomechanical factors that overload the muscles and bone along your tibia. The classic scenario is too much, too soon: suddenly increasing your running mileage, intensity, or frequency without allowing your body to adapt. Your muscles, tendons, and bone all adapt to increased loads at different rates, with bone being the slowest to strengthen. When you progress faster than your bone can adapt, you get the painful periosteal irritation characteristic of shin splints.
Running surface and footwear changes are major contributors. Switching from grass or trail running to concrete or asphalt changes the loads your legs must absorb. Similarly, running in worn-out shoes or switching to shoes with different cushioning properties can alter the loads placed on your shins. Many people develop shin splints when they start a new running program on hard surfaces after being sedentary, because their bones haven't had the gradual loading needed to strengthen appropriately.
Biomechanical factors significantly influence shin splint development. (excessive flattening of your foot) increases the load on the muscles along the inside of your shin as they work to control the foot's motion. Tight calves force these muscles to work harder to lift your foot during the swing phase of running. Hip weakness, particularly weak glutes, can alter your entire leg alignment, creating abnormal stresses throughout your lower leg. Even factors like running primarily on cambered roads or always running the same direction on a track can create asymmetric loading patterns that predispose one leg to developing shin splints.
Research
What the studies show
Shin splints (medial tibial stress syndrome) can be diagnosed reliably from questions and an examination
Two clinicians examining the same 46 athletes independently agreed on the diagnosis of shin splints (medial tibial stress syndrome) almost every time, using only questions about the symptoms and a physical examination. About a third of those with it had another lower leg injury at the same time.
Supports diagnosing shin splints in the clinic and reserving imaging for features that suggest a stress fracture or another cause.

Treatments for shin splints: a systematic review
No treatment studied was supported by trials free enough of bias to be recommended over others, including rest, which is why rehabilitation is built around loading that builds up step by step and training changes rather than one specific treatment.
Sets honest expectations: management of shin splints rests on load management and a gradual return to running rather than any single treatment.
