Why Do My Hips Hurt When I Run?

Hip pain is a frequent experience for many runners, often forcing a sudden stop to a training routine. Discomfort can range from a dull ache appearing late in a run to sharp, immediate pain suggesting a more serious injury. The hip is a complex joint that relies on the strength and coordination of many muscles, making it vulnerable to the repetitive forces inherent in running. This article covers the most common running-related hip injuries and outlines steps for acute relief and long-term prevention.

Understanding Common Running-Related Hip Injuries

Hip discomfort in runners is often categorized by its location: anterior (front), lateral (side), or posterior (back).

Anterior Hip Pain

Anterior hip pain commonly relates to hip flexor tendinopathy, an irritation of the iliopsoas tendon. This deep, aching pain is felt high in the groin and typically worsens during the swing phase of the running gait when the hip is actively flexed. This overuse injury results from excessive hip flexion load, often exacerbated by hill running or speed work.

Lateral Hip Pain

Lateral hip pain, felt on the outside of the hip bone, is most frequently diagnosed as Gluteal Tendinopathy, or Greater Trochanteric Pain Syndrome (GTPS). Although often mislabeled as trochanteric bursitis, the primary issue is usually a breakdown in the gluteus medius and minimus tendons. The pain presents as localized tenderness over the bony prominence of the hip and can be aggravated by lying on the affected side or performing single-leg activities.

Posterior Hip Pain

Posterior hip and deep buttock pain can point toward two distinct conditions: High Hamstring Tendinopathy or Piriformis Syndrome. High Hamstring Tendinopathy involves the tendons where the hamstring muscles attach to the ischial tuberosity (“sit bone”). This results in a deep ache worsened by fast running, hill climbing, and prolonged sitting. Piriformis Syndrome involves irritation of the sciatic nerve as it passes near or through the piriformis muscle. This can cause pain that radiates down the back of the leg, sometimes mimicking sciatica.

Immediate Acute Pain Relief Strategies

The first step upon feeling hip pain during a run is to immediately stop the activity to prevent further tissue damage. Continuing to push through pain often converts a minor irritation into a more significant injury requiring extended recovery time. Initial management focuses on reducing immediate symptoms like pain and swelling.

The RICE principle—Rest, Ice, Compression, and Elevation—provides a useful framework for the first 48 to 72 hours following acute pain. Applying ice to the painful area for 15 to 20 minutes several times a day helps dull pain perception and limit localized swelling. Limiting weight-bearing activity through rest is necessary to calm the irritated tissues.

Over-the-counter medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen can temporarily reduce pain and inflammation. Acetaminophen is an alternative pain reliever that may be gentler on the stomach. Use these medications only for short-term relief, typically no longer than a few days, and always according to dosage instructions. Activity modification is also important, such as avoiding crossing the legs while sitting and placing a pillow between the knees when sleeping on the side.

Correcting Underlying Muscular Imbalances and Form Issues

Addressing the root cause of running-related hip pain involves correcting deficits in muscular strength and stability, along with optimizing training habits. Running demands high-level stability from the hip abductors and core musculature to control the pelvis over the stance leg. Weakness in the gluteal muscles, particularly the gluteus medius, is a primary factor contributing to hip pain by allowing excessive pelvic drop during the running stride.

Targeted strengthening exercises are necessary to restore this stability, starting with non-weight-bearing movements. The clamshell exercise is highly effective for isolating and activating the gluteus medius and minimus, which are crucial for hip abduction. This exercise is often performed with a resistance band to ensure sufficient load and can serve as an excellent warm-up before a run. Progressing to functional, single-leg exercises is essential because running is a series of single-leg stances.

The Single-Leg Deadlift is a beneficial exercise that challenges the hip, knee, and ankle to stabilize the body on one leg, directly translating to improved running mechanics. It also strengthens the posterior chain—the glutes and hamstrings—eccentrically, teaching them to control the leg as it extends and absorbs force. By building strength in this functional pattern, the body becomes more resilient to the loads of running and less reliant on compensatory movements.

Training load management is equally important in preventing recurrence. The “10% Rule” suggests increasing weekly mileage by no more than ten percent over the previous week. This guideline ensures the body’s tissues have adequate time to adapt to new stress. Runners should also consider form adjustments, such as increasing their step rate or cadence, which naturally shortens the stride and reduces the braking forces and impact stress placed on the hip joint.

Knowing When to Seek Medical Attention

While many running-related hip pains respond well to rest and self-management, certain symptoms indicate a need for professional medical evaluation. Any pain that makes it impossible to bear weight on the affected leg, or that causes a noticeable limp during walking, requires immediate consultation. This could be a sign of a more serious structural issue, such as a stress fracture in the femoral neck.

Pain that persists or continues to worsen despite four to seven days of diligent rest, icing, and activity modification should be assessed by a healthcare provider or physical therapist. The appearance of systemic symptoms alongside hip pain is a red flag. These symptoms include unexplained fever, night sweats, or chills, which may suggest an underlying infection or inflammatory process. Neurological changes, such as numbness, tingling, or weakness radiating down the leg, also signal nerve involvement requiring professional diagnosis.
