TL;DR
Shin splints are pain along the shin bone — the tibia, the large bone in the front of the lower leg. Known in medicine as medial tibial stress syndrome, the condition is common in runners, dancers, and military trainees, and it most often shows up when athletes start training harder, because the increased activity puts stress on the muscles, tendons, and bone tissue [1]. The early pattern is distinctive: the pain is felt along the inner side of the shinbone with mild swelling, and it usually stops when you stop exercising, sometimes easing with stretching. But if the pain becomes ongoing, it may signal a stress reaction or stress fracture — a reason to see a healthcare professional, especially if rest, ice, and over-the-counter pain relievers do not ease the pain [1]. The good news is that rest, ice, and other self-care measures most often treat shin splints, and a proven set of prevention habits — the right shoes, gradual training increases of about 10 percent per week, lower-impact cross-training, and strength work — helps keep them from coming back [1] [2].
Quick Answer
What it is: Pain along the shin bone (tibia), known in medicine as medial tibial stress syndrome [1].
The cause: Continuing stress on the shinbone and the tissues that attach muscles to the bone [1].
Who gets it: Runners (especially new ones), dancers, and military trainees; it often occurs when athletes start training harder [1].
The key warning sign: At first the pain stops when you stop exercising — if the pain becomes ongoing, you may be developing a stress reaction or stress fracture [1].
Treatment in one line: Rest from painful activities while staying active with low-impact exercise, ice the shin for 15 to 20 minutes three to four times a day, and use an over-the-counter pain reliever [2].
What This Guide Is Based On
This guide is built entirely from specialist-reviewed clinical guidance updated on April 30, 2025, supported by the American Academy of Orthopaedic Surgeons' OrthoInfo patient education on shin splints, the Merck Manual Professional Version's overview of shin splints, UpToDate's review of running injuries of the lower extremity, and Brukner & Khan's Clinical Sports Medicine (5th ed., 2017), a standard reference in sports medicine.

What Are Shin Splints?
Shin splints are pain along the shin bone, also called the tibia. The tibia is the large bone in the front of the lower leg. Shin splints are common in runners, dancers, and military trainees [1].
Known in medicine as medial tibial stress syndrome, shin splints often occur in athletes when they start training harder. The increased activity puts stress on the muscles, tendons, and bone tissue [1].
What Are the Symptoms?
If you have shin splints, you might notice tenderness, soreness, or pain along the inner side of your shinbone, along with mild swelling in your lower leg [1].
Symptom feature | What it looks like |
Tenderness, soreness, or pain | Felt along the inner side of your shinbone [1] |
Inner-shin location | Pain tracks along the shinbone (tibia) [1] |
Mild swelling | Slight swelling in the lower leg [1] |
Early behavior | The pain might stop when you stop exercising and might feel better with stretching [1] |
The early pattern matters. At first, the pain might stop when you stop exercising. It might feel better with stretching. But in time, the pain can become ongoing — and that change may mean you are getting a stress reaction or stress fracture [1].
When Should You See a Doctor?
Call your healthcare professional if rest, ice, and pain relievers you can get without a prescription don't ease your shin pain [1].
What Causes Shin Splints?
Shin splints are caused by continuing stress on the shinbone and the tissues that attach muscles to the bone, called connective tissues. When activity ramps up — especially suddenly — that repeated stress on the muscles, tendons, and bone tissue is what produces the pain along the inner shin [1].
Who Is Most at Risk?
The risk of shin splints is higher for people who train hard, train suddenly, or train on unforgiving ground. The source material lists five risk factors [1].
Risk factor | What it means |
Running, especially starting a running program | New runners are especially vulnerable [1] |
Quickly increasing training | Quickly increasing how long, how often, or how hard you exercise [1] |
Hard or uneven surfaces | Running on uneven ground, such as hills, or on hard surfaces, such as concrete [1] |
Military training | Being in military training [1] |
Foot shape | Having flat feet or high arches [1] |
What Are the Possible Complications?
The main complication to watch for is progression from shin splints to something more serious. When the pain stops behaving like early shin splints — when it no longer fades at rest and becomes ongoing — you may be developing a stress reaction or stress fracture in the shinbone [1]. Catching that change early, with a healthcare professional's evaluation and imaging when needed, is what keeps a nagging shin from turning into a broken one [1] [2].
How Are Shin Splints Diagnosed?
Shin splints most often are diagnosed based on medical history and a physical exam. Sometimes, an X-ray or other imaging studies can point to other causes for the pain, such as a stress fracture [2].
In practice, that means the diagnosis is largely clinical — your story and the exam carry most of the weight — and imaging is reserved for cases where another cause like a stress fracture is suspected.
How Are Shin Splints Treated?
Most often, you can treat shin splints with simple self-care steps [2].
Self-care step | How to do it |
Rest | Don't do activities that cause pain, swelling, or discomfort — but don't stop moving. While you're healing, try low-impact exercises such as swimming, bicycling, or water running [2] |
Ice | Apply ice packs to the affected shin for 15 to 20 minutes at a time, 3 to 4 times a day for several days. Wrap the ice packs in a thin towel to protect your skin [2] |
Over-the-counter pain reliever | Ibuprofen (Advil, Motrin IB, others), naproxen sodium (Aleve), or acetaminophen (Tylenol, others) can reduce pain [2] |
Once the pain is gone, go back to your usual activities little by little [2].
How Can You Prevent Shin Splints?
Wearing the right shoes, not increasing training too quickly, and altering exercises can help prevent shin splints from coming back. The source material outlines seven practical steps [1].
Make sure you're moving right. A sports medicine professional can watch a video of you running to help find areas in which you can improve to lower your risk of shin splints. Often, small changes in how you run and exercises to build strength can lower your risk [1].
Don't do too much. Too much running or other high-impact activity done for too long, too hard can overload the shins [1].
Choose the right shoes. Use a shoe that's comfortable, well cushioned, and suited to your foot. If you're a runner, replace your shoes about every 350 to 500 miles (560 to 800 kilometers) [1].
Think about arch supports. Arch supports might help prevent the pain of shin splints, especially if you have flat arches [1].
Think about shock-absorbing insoles. They might reduce shin splint symptoms and prevent them from coming back [1].
Lower the impact. Cross-train with a sport that puts less impact on your shins — examples are swimming, walking, or biking. Start new activities slowly, and increase how long and hard you do them little by little. About a 10 percent increase in the amount of impact activity per week is a good progression [1].
Add strength training to your workout. Exercises to strengthen your legs, ankles, hips, and core can help get your legs ready for high-impact sports [1].
How Should You Prepare for Your Appointment?
Start with your family doctor or general practitioner, and call your healthcare professional if rest, ice, and over-the-counter pain relievers don't ease your shin pain. If imaging is needed to rule out a stress fracture, an X-ray or other imaging studies can point to other causes for the pain [1] [2].
Before your appointment, write down when the pain started, what activities trigger it, how your training has changed recently (mileage, intensity, surfaces), what shoes you use and how old they are, and what self-care you have already tried. Bring the list of any medications and pain relievers you have used. Your provider will likely ask about your exercise routine, recent training changes, and the exact location and behavior of the pain — having answers ready frees up time to cover what matters most to you.
Conclusion: A Common Training Injury That Usually Yields to Simple Self-Care
Shin splints — medial tibial stress syndrome — are the price the shinbone and its connective tissues sometimes pay when training ramps up too fast. The injury is common among runners, dancers, and military trainees, and its early signature is easy to recognize: tenderness, soreness, or pain along the inner side of the shinbone with mild swelling, fading when exercise stops and sometimes easing with stretching. The self-care formula is just as simple: rest from painful activities while keeping moving through low-impact exercise like swimming, biking, or water running; ice for 15 to 20 minutes three to four times a day; and over-the-counter pain relievers such as ibuprofen, naproxen, or acetaminophen. The warning that deserves attention is a change in the pain's behavior — once it stops fading at rest, a stress reaction or stress fracture may be developing, and imaging can settle the question. Prevention comes down to seven habits, led by the rule of thumb that guides most of them: increase impact activity by about 10 percent per week, wear shoes suited to your foot and replace them every 350 to 500 miles, cross-train with lower-impact sports, and strengthen your legs, ankles, hips, and core.
If your shin pain isn't easing with rest, ice, and over-the-counter pain relievers, contact your healthcare professional.

Frequently Asked Questions
What are shin splints, in simple terms?
Shin splints are pain along the shin bone — the tibia, the large bone in the front of the lower leg. In medicine the condition is called medial tibial stress syndrome, and it results from continuing stress on the shinbone and the connective tissues that attach muscles to the bone [1].
Who gets shin splints?
Shin splints are common in runners, dancers, and military trainees, and they often occur when athletes start training harder, because the increased activity puts stress on the muscles, tendons, and bone tissue [1].
What causes the pain?
Continuing stress on the shinbone and the tissues that attach muscles to the bone. Risk is higher when you quickly increase how long, how often, or how hard you exercise, when you run on hills or concrete, when you're in military training, or when you have flat feet or high arches [1].
How do I know my pain is shin splints and not a stress fracture?
Early shin-splint pain typically stops when you stop exercising and may improve with stretching. If the pain becomes ongoing despite that, you may be developing a stress reaction or stress fracture — see a healthcare professional, who may order an X-ray or other imaging to check [1] [2].
How long does it take to heal?
Most often, simple self-care steps — rest from painful activities while staying active with low-impact exercise, ice, and over-the-counter pain relievers — treat shin splints successfully. Return to your usual activities little by little once the pain is gone [2].
Should I stop exercising completely?
No. While you're healing, try low-impact exercises such as swimming, bicycling, or water running — but don't do activities that cause pain, swelling, or discomfort [2].
How do I prevent shin splints from coming back?
Wear comfortable, well-cushioned shoes suited to your foot and replace running shoes about every 350 to 500 miles; increase impact activity by about 10 percent per week; cross-train with lower-impact sports; consider arch supports or shock-absorbing insoles; get a gait check from a sports medicine professional; and strengthen your legs, ankles, hips, and core [1].
When should I call a doctor?
Call your healthcare professional if rest, ice, and over-the-counter pain relievers don't ease your shin pain [1].
