Shin Splints

A dull, aching pain along the inner shin that often shows up during or after running and feels tender to touch.

Pain Area

Inner lower shin

Medical Name

Medial Tibial Stress Syndrome

Can You Run?

Sometimes — but only if the pain is more diffuse than pinpoint, there is no limp, and symptoms settle by the next day

Typical Recovery

Usually 2 to 8 weeks, depending on how irritated it is

Common Onset

Often linked to a sudden increase in mileage, intensity, hills, or impact

Can I Keep Running?

Do not run through shin pain that is getting worse or showing up earlier in each session. Modified running is only sensible if the pain is diffuse rather than pinpoint, there is no limp, and symptoms settle by the next day.

Typical Recovery Timeline

Shin Splints usually take around 2 to 8 weeks to settle, depending on how irritated the shin is. Milder cases may keep some modified running, while more irritable cases often need a clearer reduction in impact until walking and hopping feel better.

Clinical Pathology

What's Actually Going On?

Shin Splints is a running-related overload injury that causes pain along the inner border of the shin bone (tibia).

It sits on the spectrum between an “angry shin” and a more serious bone stress injury, which is why it’s important to catch it early.

In most runners, this happens when the tissues around the shin are being asked to handle more repetitive impact than they’re currently ready for.

Common Symptoms

A dull or aching pain along the inner lower shin
Pain that may show up early in a run, then sometimes warm up
Pain that often returns after exercise
Tenderness along a larger stretch of the shin
A shin that feels irritated with repeated impact
Pain that is more spread out rather than focused in one exact spot
Load Management

Can You Still Run With It?

Sometimes, yes — but only if the pain stays more diffuse than sharp, doesn’t get worse as the run goes on, and settles by the next day.

If the pain becomes more focused, sharper, or starts affecting walking or hopping, it usually means the shin needs a clearer reduction in impact.

Easy, flat running may sometimes be tolerated in milder cases, but pushing through worsening shin pain is usually what turns a manageable problem into a bigger one.

Things That Often Need Adjusting:

01.Weekly mileage
02.Speed work
03.Hills
04.Long Runs
05.Running Frequency
Pattern Recognition

Does This Sound Like You?

  • Your shin feels sore or tender along the inside edge
  • It often hurts at the start of a run, then changes as you keep going
  • The pain comes back after running
  • The area feels irritated when you press along the shin
  • The pain is more spread out than one tiny spot
  • Your shin has started feeling less tolerant of normal running load
A big clue with Shin Splints is that it usually feels like a broad irritated shin, not one exact bony point.

Why Do Runners Get This?

This usually happens when load quietly outruns tissue capacity.

• A fast increase in: mileage
• intensity
• hill work
• Repeated impact without enough recovery
• Reduced calf or lower-leg strength
• Returning too quickly after time off
• Sometimes: footwear changes
• terrain changes
• harder surfaces

Most of the time, this is a load management and lower-leg capacity problem, not just a random flare-up.

Worth Getting Assessed If:

  • •the pain is becoming more focal
  • •it hurts to hop
  • •it starts hurting with normal walking
  • •symptoms are getting worse despite cutting back
  • •you’re unsure whether it’s still Shin Splints or something more serious

Get Help Sooner If You Have:

  • pain at rest or at night
  • sharp, pinpoint tenderness on one specific spot of the shin bone
  • pain with hopping or normal daily walking
  • symptoms that rapidly worsen over a short period

Clinical Perspective

A Note From Liesel

“If you are frustrated by medial tibial stress syndrome (shin splints), that makes sense. Running injuries are rarely hard because they are mysterious; they are hard because they interrupt identity, routine and confidence. I want you to remember that steady, boring progress still counts. Every calmer morning, every clean rep, and every sensible comeback run is a step back toward your running life”
