If it hurts, find it here.
Running pain isn't random. Where it hurts and when it hurts tell you what's actually going on. Pick a body part — then a pattern — to get a clear answer.
Browse by body part
The knee is the most-injured joint in runners. Most knee pain is mechanical — load, alignment, or weakness — not structural damage.
ExploreShin pain in runners is almost always shin splints (MTSS) or — much more seriously — a tibial stress fracture. The difference matters a lot.
ExploreFoot pain in runners spans plantar fascia, metatarsals, midfoot, and toes. Location is everything for diagnosis.
ExploreHip pain is often referred — the source can be the joint, the glutes, the deep hip rotators, or the lower back.
ExploreCalf pain in runners ranges from a tight gastroc to a partial tear. Sharp, snap-like pain needs immediate attention.
ExploreAnkle pain is usually ligament, tendon, or impingement-related. Trail runners and rolled-ankle histories drive most cases.
ExploreHamstring pain in runners is usually high (tendon, near the sit bone) or mid-belly (muscle strain). Each has a different recovery path.
ExploreAchilles pain progresses on a spectrum: morning stiffness → pain warming up → pain during runs → pain at rest. Catch it early.
ExploreIT band pain is the classic sharp outer-knee pain that turns on after a predictable distance and turns off when you stop.
ExploreLower back pain in runners is often a movement and core issue, not a spine issue. Most cases resolve with smarter loading and strength.
ExploreQuad pain in runners is usually load-related — eccentric damage from downhills or a sudden volume spike. True strains are less common.
ExploreGlute pain is often piriformis or deep hip rotator irritation. Sciatic-type referral is common.

Pain that turns on with running and turns off when you stop usually points to a load or mechanics issue. The tissue is irritated but rarely structurally damaged — yet.
Post-run pain is your tissues processing the load. Mild stiffness fading in 24 hours is normal. Pain that intensifies hours later or carries into the next day signals overload.
Pain that spikes specifically on impact is a yellow-to-red flag. Bone, joint surface, or stress reactions hurt with vertical load. This is the pattern that most often precedes stress fractures.
Downhill running multiplies eccentric load on quads, knees, and the patellar tendon. Pain only on descents usually points to strength or mechanics, not structural damage.
Pain at rest is a serious signal. Most overuse irritation calms when load comes off. Pain that persists at rest suggests inflammation, stress reaction, or a deeper structural issue.
Pain that's worst in the first 5-15 minutes and warms up is the classic tendinopathy signature. The tissue is irritated, but it's the most treatable pattern if caught early.
