Running can be a rewarding activity, but it often brings hip pain. This discomfort can range from a dull ache to a sharp sensation, making each stride a challenge. Understanding why your right hip might hurt when you run involves examining specific anatomical issues, as well as considering how your running form and training habits contribute to these problems. This article explores common culprits behind runner’s hip pain.
Specific Anatomical Causes of Hip Pain
Iliotibial (IT) Band Syndrome is a frequent cause of outer hip pain in runners. The IT band is a thick band of connective tissue running along the outside of the thigh from the hip to just below the knee. Repetitive knee bending during running can cause the IT band to tighten and rub against the outside of the knee or hip, leading to irritation, pain, and swelling. This pain often worsens with continued activity.
Hip flexor tendinitis or strain can cause pain in the front of the pelvis or groin. The hip flexors are responsible for lifting the knee towards the chest and swinging the leg forward during running. Overuse can lead to inflammation of these tendons (tendinitis) or tears in the muscle fibers (strain). This pain typically intensifies when raising the knee towards the chest or during the swing phase of running.
Trochanteric bursitis involves inflammation of a bursa on the outer side of the hip. Bursae are small, fluid-filled sacs that cushion bones, tendons, and muscles, reducing friction during movement. Repetitive friction or pressure from running can inflame this bursa, causing pain on the outside of the upper thigh or hip. This pain can worsen when lying on the affected side or with activities like stair climbing.
Piriformis syndrome results from the piriformis muscle, deep in the buttock, irritating or compressing the sciatic nerve. This muscle assists in hip rotation. When the piriformis muscle tightens due to overuse, it can press on the sciatic nerve, leading to pain, numbness, or tingling that often radiates from the buttock down the leg.
Stress fractures are tiny cracks in a bone caused by repetitive microtrauma, occurring in the hip or pelvis. These are serious causes of hip pain in runners, often appearing after a rapid increase in mileage or intensity. Symptoms include an aching pain in the hip, groin, or front of the thigh that worsens with activity and may improve with rest.
Running Form and Training Factors
Improper running biomechanics can significantly contribute to hip pain. Overpronation, where the foot excessively rolls inward after landing, can alter leg alignment and place increased stress on the hip. A cross-over gait, where legs cross the body’s midline while running, also increases stress on the lower leg, knee, and hip. Additionally, excessive hip drop, where the pelvis tilts downwards on the non-stance leg, indicates weakness in the hip abductor muscles and can lead to discomfort.
Muscle imbalances or weakness, particularly in the gluteal muscles and hip abductors, frequently cause hip pain in runners. Weak glutes can lead to poor posture, increasing pressure on the lower back and affecting hip mechanics. Tight hip flexors, often from prolonged sitting, can limit hip mobility and force other muscles to compensate, disrupting proper running form. These imbalances compromise the hip’s stability and shock absorption during running, increasing the likelihood of overuse injuries.
Overtraining or a rapid increase in mileage and intensity can overwhelm the body’s ability to adapt and recover, leading to overuse injuries, including hip pain. Suddenly increasing running distance or introducing speed work without gradual progression can push muscles and connective tissues beyond their limits. This can result in muscle pain, stiffness, tendinitis, or bursitis.
Inadequate warm-up or cool-down routines also play a role in injury development. A proper warm-up prepares the body, increases blood flow to muscles, and improves joint mobility, reducing the risk of strains. Skipping a cool-down can lead to muscle stiffness and soreness, hindering recovery and increasing susceptibility to injury.
Improper or worn-out footwear can significantly impact running mechanics and contribute to hip pain. Shoes lacking adequate support or cushioning can alter gait, forcing the hips to work harder for stabilization. Worn-out shoes lose shock absorption, increasing impact on joints, while shoes with incorrect pronation support can exacerbate misalignment issues.
Running on uneven or hard surfaces places additional stress on the hip joint. Uneven terrain demands more stabilization from ligaments, tendons, and muscles. Hard surfaces like asphalt or concrete increase impact forces transmitted through the legs to the hips. These environmental factors can exacerbate existing biomechanical issues or induce new stresses, contributing to hip pain.
Recognizing When to See a Doctor
While many running-related pains can be managed with self-care, certain symptoms warrant professional medical evaluation.
- Severe or sudden hip pain, especially if it occurs acutely during a run.
- Pain that worsens or persists despite rest, ice, and activity modification, or interferes with daily movements.
- Pain accompanied by swelling, bruising, or visible deformity around the hip joint.
- An inability to bear weight on the affected leg, or significant limping.
- Numbness, tingling, or weakness in the leg or foot along with hip pain, indicating possible nerve involvement.
- Fever or chills accompanying hip pain, which may point to an infection.
- Hip pain that disrupts sleep, even when at rest, potentially a symptom of stress fractures.

Immediate Steps for Relief
When experiencing acute right hip pain during a run, immediate steps can provide relief.
- Rest the affected area by stopping running and any other activities that aggravate the pain.
- Apply ice to the painful area for 15-20 minutes, several times a day, especially in the first 24-48 hours, to reduce inflammation.
- Gently stretch hip flexors, glutes, and the IT band if pain allows. Avoid stretches that increase discomfort.
- Consider over-the-counter pain relievers, such as NSAIDs like ibuprofen, to manage pain and inflammation. Consult a doctor or pharmacist first.
- Modify activity temporarily. Engage in low-impact exercises like swimming or cycling that do not stress the hip.
These immediate steps are for initial relief and are not a substitute for diagnosing or treating the underlying cause of hip pain.
