Shin splints from running are an overuse injury that inflames the shinbone and nearby tissues, usually after harder or changed training. Rest, ice, low-impact activity, supportive shoes, and a slow return to running form the core plan.
Medial tibial stress syndrome is the medical name for shin splints. It causes dull aching pain along the front or inner shin. The pain often rises during a run and eases with rest.

Why does running cause shin pain?
Repetitive stress is the main driver. Each foot strike loads bone, muscle, and connective tissue. Too much load too soon leaves these tissues sore. Risk rises after a jump in mileage, speed, hills, or hard surfaces.
New shoes, worn shoes, or a switch to track or road work can also add strain. According to Mayo Clinic, runners who recently intensified or changed training face higher risk, as do people with flat feet or high arches, described in Mayo Clinic's causes overview. Foot shape affects how force spreads through the lower leg. Flat feet can roll inward and stretch inner-leg tissues. High arches can absorb less shock and pass more force to the shin.
What does it feel like?
The usual sign is a dull ache along the shin during or after running. The area may feel tender to touch, with mild swelling. UC Davis Health notes that pain typically worsens during running and eases with rest, as explained in UC Davis Health's running injury guide. Pain in both legs points more toward shin splints.
Sharp pain in one small spot, pain at night, or pain while walking deserves closer attention. Those patterns can signal another injury. Keep brief notes on distance, surface, shoes, and pain level. A one-week log often reveals the trigger. Bring it to a clinic visit if pain persists.
How should you treat it early?
Stop impact activity until walking and daily movement feel calm. Ice the shins for 15 to 20 minutes, three to four times daily, for several days. Mayo Clinic recommends this rest-and-ice start plus short-term low-impact training such as swimming, cycling, or water running, detailed in Mayo Clinic's treatment guidance.
Over-the-counter pain relievers may reduce discomfort for some runners. They do not repair overloaded tissue. If rest, ice, and simple measures fail, seek medical advice.
- Pause running and jumping until shin pain settles.
- Ice 15 to 20 minutes, 3 to 4 times daily, for several days.
- Use swimming, cycling, or water running to stay fit.
- Return to impact only when daily walking is pain-free.
How do you return to running safely?
Resume only after pain settles, ideally with clinician approval. Start with easy run-walk sessions on soft, flat ground. Add distance slowly before adding speed or hills. A clinician may review training load, shoes, and running mechanics.
Video gait analysis sometimes helps spot heavy overstriding, low cadence, or excess inward roll. Small form and shoe changes can then lower shin stress. Stop the session if shin pain returns and builds. Take an extra rest day, repeat the prior easy step, and cross-train instead. Steady progress over two to four weeks beats one hard test run.
How can you prevent the next episode?
Wear supportive running shoes that match your feet and replace worn pairs. Runners with flat feet may benefit from shock-absorbing insoles or orthotics. Cleveland Clinic lists supportive footwear, insoles or orthotics for flat feet, calf stretching, lower-leg strengthening, and slow training progression as key defenses. Build weekly mileage in small steps and keep hard days apart.
Mix road, track, trail, and softer surfaces when possible. Add calf raises, toe walks, and ankle-strength work two or three times weekly. Persistent shin pain may be a stress fracture rather than shin splints, so imaging is sometimes needed to separate the two. Seek prompt care for severe pain, visible swelling, numbness, or pain that does not improve with rest.
