- Shin splints are pain and inflammation along the inner edge of the shinbone (tibia) caused by repetitive stress on the muscles, tendons, and bone covering.
- They are most common in runners, jumpers, dancers, and patients who recently ramped up training too quickly.
- Symptoms must be distinguished from stress fractures, compartment syndrome, and tendinitis — the wrong diagnosis leads to the wrong treatment.
- Conservative care — activity modification, ice, supportive shoes, custom orthotics, and structured return-to-running — resolves most cases in 2–6 weeks.
- Running through shin splints risks turning them into a true stress fracture.
What are shin splints?
Shin splints — formally called medial tibial stress syndrome (MTSS) — is the catch-all term for pain along the inner edge of the shinbone in active people. It is caused by repetitive loading of the muscles that attach to the tibia, combined with stress on the bone's outer covering (periosteum). The result is a diffuse, achy pain along several inches of the inner shin that's worst with running or jumping.
It is one of the most common overuse injuries we see in runners — particularly new runners, runners who increased mileage too quickly, or experienced runners returning after time off. Flat feet, very high arches, tight calves, worn-out shoes, and hard training surfaces all increase the risk. Dancers and jumping-sport athletes are also frequently affected.
At Northwest Extremity Specialists, our priority on the first visit is to make sure it's actually shin splints — not a stress fracture, compartment syndrome, or nerve entrapment, all of which present similarly but need very different treatment. Once the diagnosis is confirmed, our sports medicine podiatrists build a stepped plan to get you back to running without restarting the cycle.
What it feels like
Shin splints have a recognizable pattern. Common features:
- Diffuse, achy pain along the inner (medial) edge of the shinbone
- Pain that's worst at the start of a run, sometimes loosening up mid-run, then returning afterward
- Tenderness when you press along several inches of the inner shin
- Mild swelling along the painful area
- Pain that's better with rest and worse with continued activity
- Symptoms that improve over hours after a workout, then return with the next session
- A pain that's diffuse — not a single sharp point (which would suggest stress fracture)
Why it develops
Shin splints develop when load exceeds the tibia's ability to recover. Common contributors:
- Sudden increase in running mileage, speed, or hill work — the classic "too much, too soon"
- Returning from a layoff without ramping back up gradually
- Worn-out or unsupportive running shoes
- Flat feet that overpronate, increasing stress on the medial tibia
- Very high arches that don't absorb shock
- Tight calf and Achilles complex
- Running on hard surfaces (concrete) exclusively
- Beginner runners building base mileage too aggressively
- Military recruits during basic training (well-documented high-risk group)
How we diagnose shin splints
Shin pain in a runner needs a careful evaluation because shin splints, stress fractures, and chronic exertional compartment syndrome all present similarly. We start with a focused history — when the pain started, how it relates to activity, exactly where it hurts. The exam includes palpation of the tibia, calf flexibility, gait analysis, and tests to distinguish bone from muscle pain. On-site digital X-ray is used to rule out an obvious stress fracture; MRI is the gold standard when a stress fracture is suspected but X-rays look normal. Most patients leave the first visit with a confirmed diagnosis and a written plan.
Non-surgical care
Almost all shin splints resolve with structured conservative care. Our typical first-line plan:
- Relative rest — back off the high-impact training, not necessarily all activity
- Cross-training (swimming, cycling, elliptical) to maintain fitness during recovery
- Ice along the painful area for 15–20 minutes after activity, 2–3 times daily
- Anti-inflammatory medication for symptom control
- Calf and arch stretching, eccentric calf strengthening
- Supportive running shoes that match your foot type and gait
- Custom orthotics when biomechanical factors are contributing
- A graduated return-to-running plan, often starting with run/walk intervals
- Physical therapy for stubborn cases or when biomechanics need a closer look
When to see a specialist
- Shin pain that has lasted more than a week and isn't improving with rest
- Sharp, point-tender pain at a single spot on the shin (could be stress fracture)
- Shin pain that wakes you at night
- Shin pain plus swelling, especially with skin redness or warmth
- Numbness, tingling, or foot drop with exercise (could be compartment syndrome — urgent)
- Recurring shin splints every running cycle — biomechanical workup is warranted
Shin splints are evaluated and treated by any of our podiatrists, but our sports medicine specialists handle a particularly high volume — Dr. Todd Galle at Tigard Oleson, Dr. Manny Moy at Milwaukie, and Dr. Magnus Schlyer at Wilsonville. Cases requiring detailed biomechanical analysis or in-depth gait work are typically coordinated with physical therapy at our Tigard Oleson clinic.
