Hip osteoarthritis
Adults over 50, and younger adults with past FAI, dysplasia or injuryWorn cartilage makes each step painful as weight passes through the joint. The body shifts weight off the hip to protect it, which causes a limp. Pain is usually felt in the groin and may travel to the thigh or knee.
The clue: Groin pain with walking that improves with rest, plus a limp and stiffness, is the classic pattern.
Gluteal tendinopathy or tear
Women over 40, runners and walkers who increased distance quicklyThe gluteal muscles keep the pelvis level with every step. When their tendons are irritated or torn, walking causes outer hip pain and the pelvis may dip. Hills and stairs are usually hardest.
The clue: Outer hip pain with walking and a pelvis that drops when standing on that leg points to the gluteal tendons.
Lumbar spinal stenosis
Adults over 60Narrowing of the spinal canal squeezes nerves when you stand and walk upright. It causes heaviness, aching or tingling in the buttocks and legs. Bending forward or sitting opens the canal and relieves symptoms.
The clue: Leg pain with walking that eases by sitting or leaning on a cart points to the spine.
Labral tear or FAI
Active adults roughly 18 to 50Walking on flat ground is usually comfortable, but pivoting, longer walks and inclines can pinch a torn labrum. A deep groin ache may follow activity.
The clue: Groin pain with walking that also catches or clicks when turning suggests a labral tear.
Stress fracture
Runners, military recruits and women with low bone densityA small crack in the femoral neck or pelvis causes pain that increases with each step. Ignoring it can lead to a complete fracture. Early X-rays may look normal, so an MRI is often needed.
The clue: Groin pain that gets worse with each step and started after increased running needs prompt imaging.
Poor circulation (peripheral artery disease)
Adults over 60, smokers and people with diabetesNarrowed arteries can cause cramping in the buttock, thigh or calf with walking. It improves quickly with standing still. This needs evaluation by a primary care doctor or vascular specialist.
The clue: Cramping that stops within minutes of standing still, without sitting or leaning forward, suggests circulation.
