An ache along the inner edge of your shinbone that shows up when you run, walk fast or chase a dink is usually shin splints, and usually it settles with a few weeks off the trigger and a slower way back. The care with the most support is relative rest and a graded return. The harder part is telling shin splints from a stress fracture or compartment syndrome, because the first steps differ. This guide covers both, and what the research says about the add-ons.
What are shin splints, and how do they differ from a stress fracture?
Shin splints, medically medial tibial stress syndrome (MTSS), is pain along the inner border of the tibia where muscles attach to the bone. The American Academy of Orthopaedic Surgeons (AAOS) describes it as inflammation of the muscles, tendons and bone tissue around the tibia, brought on by repetitive activity. The StatPearls review (updated December 2025) calls it an early point on a continuum of bone stress injuries that can advance to a stress fracture if you keep loading it.
| Condition | Where and how it hurts | What to do |
|---|---|---|
| Shin splints (MTSS) | Diffuse tenderness along more than 5 cm of the inner shin; hurts during or after activity, eases with rest | Relative rest, graded return |
| Tibial stress fracture | Tenderness at one spot, under 5 cm; may hurt walking or at night | See a doctor; imaging, often MRI |
| Chronic exertional compartment syndrome | Tight, cramping or burning pain that starts a set way into exercise, usually in both legs, eases soon after stopping | See a doctor; pressure testing confirms it |
| Acute compartment syndrome | Pain out of proportion, worse when the muscle is stretched, tense calf | Emergency care |

What are the warning signs that it is not shin splints?
Stop running and see a doctor if the pain is in one spot you can cover with a fingertip, if it hurts when you walk or lie in bed, or if you have numbness, tingling or a tight, bulging calf. These point toward a stress fracture or compartment syndrome, both of which need an exam before you load the leg again.
Use this as a checklist:
- One painful spot. StatPearls separates a stress fracture by point tenderness along less than 5 cm of the tibia, against more than 5 cm for shin splints. AAOS adds that a hop on the leg may reproduce the pain.
- Pain at rest. AAOS lists limping, aching in bed at night, swelling and bruising as signs a bone stress injury has progressed.
- Tightness, burning or tingling that starts mid-run and fades after. The StatPearls review of exertional compartment syndrome describes squeezing, cramping or burning that begins within 15 to 20 minutes of exercise, in both legs in 70 to 95% of cases. Pain that eases soon after stopping is also how AAOS describes the chronic form.
- A pain out of proportion that does not ease. The acute form is a surgical emergency, and the same review says irreversible muscle and nerve damage can occur after just a few hours. Go to an emergency department.
- No improvement after rest. AAOS says to see a doctor if shin splints do not improve with rest and basic care, to check for another cause.
A plain X-ray is often normal in an early stress fracture, so StatPearls names MRI as the preferred scan.
What raises your risk of shin splints?
The biggest trigger is a sudden jump in how much you do. AAOS lists changes in frequency (more days a week), duration (longer distances) and intensity (hills after flat ground), plus flat feet or rigid arches and worn-out or wrong shoes. Runners have the highest risk, followed by dancers and military recruits.
Two points sharpen that list:
- A new season counts as a jump. AAOS notes bone stress injuries often appear 3 to 4 weeks after starting a new routine, and gives the example of someone who walks little at home and walks far more on vacation.
- Bone health and fuel matter. StatPearls links lower bone density and a smaller tibial cross-section to MTSS, and reports that vitamin D deficiency raised stress injury risk in military recruits. AAOS adds low energy intake, under 7 hours of sleep, no rest days, hard surfaces and worn shoes. That work is in recruits, so ask your doctor before supplementing.
What is the best shin splints treatment to start with?
Start with several weeks of rest from the activity that caused it, swapping in swimming, an exercise bike or an elliptical. AAOS also lists ice for 20 minutes at a time, anti-inflammatory medicine for pain, an elastic compression bandage for swelling, cushioned shoes, and shoe inserts if you have flat feet or repeat episodes.
The evidence for rest is thinner than the advice. StatPearls says there are no specific recommendations for how long to rest, and the 2012 randomized trial of 74 athletes never compared a graded running program with complete rest, so it cannot say which is better. What the trial did show is the timeline: groups took about 102 to 118 days on average to complete a running program, with nearly 19% dropping out for lack of progress. Plan on months. That is one trial of Dutch athletes in many sports, so your timeline may differ.
On orthotics, StatPearls cites one trial in which arch-support inserts beat sham inserts for recovery at 6 to 18 weeks. A 2025 meta-analysis of prevention trials found overpronation insoles reduced MTSS (moderate certainty), while shock-absorbing insoles did not (high certainty).
Do strengthening exercises help shin splints?
Strength work does not clearly speed recovery, but it has the better case for preventing a return. In the 2012 trial, adding calf stretching and strengthening to a running program made no difference to time back to running. A 2025 trial of 40 runners found added lower-leg exercises did not reduce pain, though foot posture and quality of life improved.
For prevention, the 2025 meta-analysis found neuromuscular training reduced MTSS in four studies of 3,887 people (high certainty), and found no evidence for static stretching. AAOS makes the mechanism plain: weak muscle absorbs less force, so more goes through the bone. A sensible plan trains the calf, the muscles at the front of the shin and the hip. StatPearls recommends all three.
What do reviews say about shockwave, laser and compression?
Evidence for every add-on is limited. A 2013 systematic review of 11 trials found all the randomized ones at high risk of bias and concluded that none was free enough from bias to recommend any treatment. Its searches ended in June 2012, so treat it as a snapshot.
| Add-on | What the evidence shows |
|---|---|
| Focused shockwave | The review judged it the most promising. A 2012 two-hospital study of 42 athletes found full recovery in about 60 days with shockwave plus a running program, against about 92 days with the program alone. It was not randomized. A 2024 review of 56 studies said the best studies suggest shockwave may work as an add-on to exercise for MTSS, and called for more high-level research. |
| Laser | The 2013 review listed low-energy laser among treatments not proven effective. A sham-controlled laser trial it covers found no faster return to duty. None of the sources above tested a Class IV laser. |
| Compression stockings | In the 2012 trial, stockings added to a running program did not change time to finish it. The 2013 review also lists them as not proven. |
| PEMF | Listed as not proven in the 2013 review. |
I found no MTSS trial of red light, pneumatic compression boots, an infrared sauna or a cold plunge in the sources reviewed here. A missing trial does not prove they do nothing. It does mean the studio's other services have no shin-specific evidence behind them.
How do you return to running after shin splints?
Return slowly, on a level surface, three days a week with a rest day between, and keep the pain low. AAOS says to be pain-free for at least 2 weeks before going back, and to return with shorter and easier sessions than before. StatPearls notes there is no proven best protocol, only a consistent theme: pain-free walking first, then low-impact work, then more distance before more speed.
This table is an illustration built from the 2012 trial and the AAOS and StatPearls guidance: a sketch to discuss with your clinician, who may set it differently.
| Stage | What you do | Move on when |
|---|---|---|
| 0 | Walk and cross-train (bike, pool) | Walking is pain-free, and AAOS's 2 pain-free weeks have passed |
| 1 | 5-minute walk, then 2 minutes jogging and 2 minutes walking, repeated four times; 3 days a week | The whole session stays under 4 out of 10 and the shin is calm the next morning |
| 2 | Same pattern with 3-minute jogs and 2-minute walks, about 20 minutes | Same check, for a full week |
| 3 | 15 to 20 minutes of continuous easy jogging | Same check |
| 4 | Add distance, about 10% at a time, before any speed or hills | Pain stays away at each step |
Built from Moen 2012, AAOS and StatPearls 2025; the staging and week counts are ours.
If pain returns, AAOS says to stop, ice and rest a day or two, then restart shorter and slower. The 2012 trial used the same rule: a score of 4 or more during or after a session, including the next day, meant staying at that stage and cutting 2 minutes. If you play pickleball or walk for exercise, follow the same ladder with walking minutes first, and add stop-start court play only after steady jogging is comfortable. That last step is a reasonable inference, not a studied protocol.
Where do studio services fit?
Studio services sit beside the plan and never replace it. Your base is a load you can tolerate, shoes that fit, a progression that holds and a doctor's exam if anything on the warning list applies. If your doctor has cleared you and wants to add something, OutRecover offers the options below, and none has proven results for shin splints.
- Shockwave has the most MTSS evidence of any add-on, and still limited. OutRecover's focused shockwave page lists tendon and overuse problems, plantar fasciitis and chronic muscle pain as uses, not shin splints by name, and says it is not recommended over open wounds, infections or tumors. The full research is on the shockwave evidence page. OutResolve is the package that includes it, built for chronic tendon pain, so it fits only if a clinician points you there.
- OutTrain is for runners, pickleball players and other athletes who want recovery sessions in a training week. It bundles red light, compression, infrared sauna, a dry cold plunge and a body scan. Treat it as a recovery routine rather than a shin treatment.
- OutFlex pairs PEMF, Class IV laser and red light for sports injuries and calf strains. It fits if your clinician finds the calf muscle is part of the problem. For the laser evidence generally, see our laser therapy guide. For the compression boots, see compression boots benefits.
For the sport itself, see our pickleball injuries guide; heel or Achilles pain has its own guides on plantar fasciitis and Achilles tendinitis.
What should you do this week?
Sort out what you have, then dial the load down.
- Press along your shin. A diffuse stretch over a hand's width points to shin splints; one spot under a fingertip, pain at night, or numbness means a doctor visit first.
- Replace running or fast walking with cycling or swimming for a few weeks.
- Check your shoes for wear and your recent weeks for a training jump.
- Start the table above only when walking is pain-free.
- If nothing improves after rest, book an exam and bring this guide's sources.
