Shin Splints: Why Your Shins Hurt When You Run

Shin splints show up every September, when people restart running after a quiet summer. Here is what actually causes shin pain, how a physiotherapist treats it, and how to tell shin splints apart from a stress fracture before it costs you a season.

Every September, the same complaint walks into our clinics. Someone started running again after summer. Two weeks in, the front of their lower leg aches. By week three, the ache arrives earlier in every run.

That pattern usually means shin splints. It is one of the most common overuse injuries in runners, and it responds well to the right plan. It also gets worse fast when people push through it.

This guide explains what shin splints are, what causes them, and how a physiotherapist treats them. It also covers the warning signs that point to something more serious than shin splints.

The short answer

  • Shin splints cause pain along the front or inside edge of your lower leg.
  • Repeated pounding on hard surfaces is the usual cause.
  • Doing too much too soon is the single biggest trigger.
  • Most cases settle with load management, better footwear, and strength work.
  • Pain that stays sharp in one small spot needs a proper assessment.
  • You do not need a doctor’s referral to see a physiotherapist in BC.

What are shin splints?

Shin splints cause pain and sometimes swelling in the front part of your lower leg. The pain comes from repeated stress on the shin bone, called the tibia, and on the tissue that joins muscle to that bone. HealthLink BC describes it as a stress problem rather than a single injury.

The pain often starts as a dull ache at the beginning of a workout. Many people find it fades once they warm up. That fading feeling convinces runners to keep going.

Left alone, the pain sharpens. It starts lasting the whole session. In stubborn cases it carries on after you stop.

What causes shin splints?

Shin splints sit in a wider family of overuse injuries. These happen when you stress a tissue repeatedly without giving it time to recover.

Several things push a shin over that line. Usually two or three stack up at once.

Shin splints or a stress fracture?

This is the question worth getting right. A stress fracture is a hairline crack in the bone. Repeated loading causes it, so it shows up in the same runners for the same reasons.

The pain pattern differs, though. Shin splint pain spreads along a stretch of the shin. Stress fracture pain concentrates in one small, tender point.

Stress fracture pain also gets worse after every session rather than better. A physiotherapist can screen for this and refer you on for imaging if needed.

Get your shin assessed if:

  • You can press one small spot on the bone and it hurts sharply.
  • The pain wakes you at night or hurts when you walk.
  • Pain gets worse after each run instead of settling.
  • The shin looks swollen, red, or feels hot.
  • Your calf feels tight, numb, or unusually weak.
  • Two weeks of rest changed nothing.

How to treat shin splints

Most shin splints settle without anything dramatic. The trick is doing the boring parts consistently.

1
Cut the load, do not stop moving. Keep exercising at a level that does not hurt. Swimming and cycling keep your fitness while your shin calms down.
2
Ice the sore area. Apply ice or a cold pack for 10 to 20 minutes, three or more times a day. Elevate the leg while you do it.
3
Stretch the calf. Tight calves change how your foot lands. HealthLink BC has a simple calf stretch you can do against a wall.
4
Sort out your shoes. Pick footwear with good arch support and a cushioned sole. If you use an insert, wear it in both shoes even when only one leg hurts.
5
Build strength through the calf and hip. Stronger legs absorb landing forces better. A physiotherapist will pick the right starting load for you.
6
Return gradually. Start slow and short. Add a little each week, and change only one thing at a time.

How physiotherapy treats shin splints

Rest alone often works. It also often fails, because rest does not fix the reason the shin got overloaded.

A physiotherapist starts by watching how you move. They look at ankle range, calf strength, hip control, and how your foot strikes the ground. That assessment points to the actual driver.

From there the plan usually has three parts. Settle the pain, load the tissue properly, then rebuild your running.

Hands-on treatment eases the calf and shin. Graded strength work through active rehabilitation makes the leg tolerate more. A kinesiologist can then build the return-to-running progression.

If your arches collapse when you land, custom orthotics may help. We fit them only when the assessment supports it. For competitive runners, our sports rehab team handles the return-to-sport side.

Why fall is peak shin splint season here

September changes how the Lower Mainland moves. School sports restart. Soccer and cross-country seasons begin. Plenty of adults dust off their runners after a quiet summer.

The weather shifts too. Trails around Metro Vancouver turn wet and slick, so people move onto sidewalks and roads. That swap alone increases impact.

Daylight shrinks as well, which pushes runs into shorter windows. Shorter windows tempt people to run harder rather than longer. All three changes hit the shins at once.

Similar overload patterns drive other lower-leg problems. If your pain sits lower, read our guides to Achilles tendonitis and plantar fasciitis.

Frequently asked questions

How long do shin splints take to heal?

Most people feel better within a few weeks once they reduce the load. Stubborn cases take longer, especially if you keep running through the pain. Getting it assessed early usually shortens the whole process.

Can I keep running with shin splints?

You can usually keep exercising, as long as it does not hurt. That often means fewer runs, shorter runs, and softer surfaces. Swimming and cycling protect your fitness in the meantime.

Do I need a doctor’s referral to see a physiotherapist in BC?

No. You can book directly with a physiotherapist in British Columbia. Many extended health plans cover the visit, and our clinics bill most insurers directly.

Are shin splints and stress fractures the same thing?

No. Shin splints involve stress on the bone and surrounding tissue. A stress fracture is an actual hairline crack, and it needs a different plan. Sharp pain in one small spot is the main clue.

Do orthotics fix shin splints?

Sometimes. Inserts help most when flat arches or poor foot support contribute to the problem. They work best alongside strength work, not instead of it.

Should I stretch or strengthen?

Do both. Calf stretching eases tightness that changes your landing. Strength work builds the capacity that stops the pain returning.
