One of the most frequent (and irritating) questions that runners field from their non-running friends and family members is, “How do you do all that running without hurting your knees?” Fortunately, despite the common myth that running is bad for your knees, most runners can confidently report that their knees are fine.
With that said, runners aren’t universally free from battling running injuries, and while the knees might garner most of the public attention and worry, hip pain after running can be nearly as prevalent if not more debilitating.
To help you identify the possible causes of hip pain after running, we’ve compiled a guide to hip pain in runners, including the likely causes and how to fix and prevent hip pain after running.
We will cover:
- Hip Pain In Runners
- Hip Pain After Running? Here Are The Likely Causes
- Risk Factors For Hip Pain In Runners
- Preventing and Treating Hip Pain After Running
Let’s get started!
Hip Pain In Runners
The hips are massive joints with numerous muscular and ligamentous attachments, so the hips are not only vital to sustaining a strong, efficient, and powerful running stride but are also at risk for various musculoskeletal injuries.
Before we cover common causes of hip pain in runners, it’s helpful to review the basic anatomy of the hips.
The hips are the largest synovial joints in the body and have a ball-and-socket configuration wherein the head of your femur (thigh bone) articulates into the concave acetabulum (socket) formed by the bones of the pelvis.
The ball-and-socket configuration makes the hip highly mobile, allowing for forward flexion and backward extension, lateral abduction (out to the side) and adduction, and internal and external rotation.
The hip joint is controlled by several large and small muscles, which work together to carry out these movements in a controlled and powerful fashion.
While you don’t need to be an anatomy buff or memorize every muscle to prevent hip pain after running, the takeaway is that hip motions are highly complex, and it’s important for runners to engage in a well-rounded routine of exercises that increase the strength and mobility of the hip musculature.
Hip Pain After Running? Here Are The Likely Causes
If you are having hip pain after running, it’s crucial to identify the cause as soon as possible before it escalates into a more serious running injury or causes additional injuries further down the kinetic chain to your knees, shins, ankles, and feet due to compensations or biomechanical alterations in your running stride.
The hips play a key role in every single step you take while you run. They form the root of your lower limbs, so your hips power and control your entire running stride.
Hip pain in runners may be due to damage to the muscles, tendons, ligaments, bones, cartilage, or bursa due to overuse or acute injury. The most common causes of hip pain after running include the following:
#1: Trochanteric Bursitis
When you run, structures in the hips such as bursa and cartilage reduce friction to enable a smooth and comfortable stride.
The trochanteric bursa is a fluid-filled sac at the top of the femur (thigh bone). The repetitive motion of running can irritate this bursa, leading to painful inflammation of the sac, termed trochanteric bursitis.
Runners with hip pain on the outside of the hip that gets worse with running, walking, climbing stairs, getting up from a low chair, or out of a car should consider this potential injury. The pain usually increases if you press on the side of your hip or try to lie on that side when you sleep.
#2: Hip Flexor Strain
The general consensus from research is that the most common causes of hip pain in runners are muscle strains and tendonitis. These injuries usually result from sudden directional changes, sudden acceleration/deceleration maneuvers, or eccentric contractions.
Runners tend to have chronically tight hip flexors, especially if they sit at a desk. If you have pain at the front of your hip in the soft tissue where your thigh meets your trunk, particularly if it’s more superficial than deep (deep is more likely iliopsoas), it might be a hip flexor strain.
#3: Iliopsoas Tendonitis
Pain in the front of the hip or groin while running, lifting your leg up, climbing stairs, and getting out of a car may be indicative of iliopsoas tendonitis. The pain may also radiate to the knee.
This hip injury in runners is usually due to overuse, particularly after an increase in speed workouts or running mileage. It often has a gradual onset, with the pain initially subsiding after you are done running but eventually progressing to lingering at rest.
#4: Hip Joint Impingement
Hip joint impingement, referred to as femoroacetabular impingement, leads to hip pain after running and during running, which may also radiate to the groin. The hip pain is due to inflammation that occurs in the ball-and-socket joint of the hip from excessive internal rotation of your hips when you run.
This inflammation results in a painful pinching of the nerves or ligaments in the hip joint. The pain usually develops gradually over several weeks.
#5: Iliotibial Band Syndrome
The IT (iliotibial) band is a thick band of fibrous connective tissue that runs down along your outer thigh from the hip to just below your knee on the side of your shin. The IT band crosses both the hip and knee joints and is a structure prone to injuries in runners.
IT band syndrome is an inflammatory condition marked by tightness, pain, and increased friction at either the hip joint, knee joint, or both. There is sometimes a clicking sensation.
#6: Hip Arthritis
Hip arthritis is a degenerative condition that refers to a thinning of the cartilage between the bones of the hip joint. It can cause rubbing and crepitus in the joint and has a gradual onset.
#7: Hip Stress Fracture
A stress fracture of the femoral neck or hip is an overuse injury. Runners with poor bone density are at increased risk of this hip injury. Pain may radiate to the groin.
#8: Labral Tears
The hip joint socket is lined with strong, flexible cartilage called the labrum. This cartilage can tear from repetitive overuse, which can lead to a constant dull ache at rest and sharp, stinging pain while you are running.
Runners may also feel a catching, clicking, or locking sensation, with or without the feeling of hip instability while running.
You may also experience hip pain after running, which may calm down after several hours.
#9: Muscle Pulls or Tears
Injuries to the quads, hamstrings, and glutes can cause hip pain while running. The location of the pain can clue you into the damaged muscle. Pain in the back bottom of the thigh may be a hamstring injury. The quads are in the front of the thigh.
Risk Factors for Hip Pain In Runners
There are several training errors and risk factors for hip injuries from running, including the following:
- Sudden increases in mileage or speed work
- Not warming up prior to a workout
- Osteoporosis and/or inadequate caloric and nutrient intake
- Excessive downhill running
- Poor running form
- Weak glutes
- Muscle imbalances
- Leg length discrepancies
- Tight hips
- Running on sloped/cambered roads
- Overtraining or insufficient rest and recovery
Preventing and Treating Hip Pain After Running
Treating hip injuries from running usually involves some amount of rest, with the potential for low-impact cross-training so long as it is pain-free. Depending on the diagnosis, ice, heat, and physical therapy might be recommended. Surgery is sometimes implicated, depending on the type and severity of the injury.
In terms of returning to running and preventing hip pain, runners should implement the following practices:
It’s crucial to warm up before jumping into your workout in order to increase circulation to your tissues. Cold tissues are tight, and this limited range of motion can cause muscle pulls or tendon strains.
#2: Run On Even Surfaces
Cambered roads, which slope from side to side, put your hips at different levels, increasing the stress on your hips and pelvis. Try to run on level footing or run on a track or treadmill until your hip pain after running subsides.
Moreover, both downhills and trails put excessive strain on the adductors and hips due to the increased demand to stabilize the pelvis.
#3: Get New Running Shoes
The general advice is to replace your running shoes every 300-500 miles to ensure optimal support. Worn-out shoes can increase your risk of hip pain while running because they lack the cushioning and support you may need.
#4: Progress Gradually
Overtraining and sudden increases in mileage and intensity put you at a greater risk for hip injuries from running. Heed the 10% rule, meaning you should only increase your mileage by a maximum of 10% from one week to the next. For example, if you are currently running 25 miles a week, run no more than 27.5 miles next week.
It’s also important to pay attention to jumps in intensity. Hip flexor strains often follow hard workouts, so ensure you give your body ample recovery between hard efforts.
#5: Improve Your Diet
To promote healthy bones and recovery from workouts, make sure you are getting enough calcium, vitamin D, protein, and total calories through your diet. Consider speaking with your doctor or sports nutritionist if you have concerns.
#6: Strengthen Your Core and Hips
Studies show that hip muscle weaknesses and imbalances increase the risk of hip injuries in runners. A weak core also leads to instability of the pelvis, which puts extra strain on the hips and pelvis.
Examples of hip strengthening exercises for runners include the following:
- Single-leg Romanian deadlifts
- Kettlebell swings
- Rear-elevated split squat
- Leg press
- Hamstring curls with a stability ball
- Side leg raises
- Resistance band lateral walks
- Single-leg glute bridges
- Barbell hip thrusts
- Lateral lunge
- Banded hip marches
- Lateral step-ups
- Inner thigh ball squeezes
- Speed skaters with a lateral slide board
#7: Do Mobility Work
Tight hip flexors, hamstrings, quads, glutes, IT band, hip abductors, adductors, and internal and external rotators increase the risk of hip injuries in runners.
Ensure you are stretching frequently, especially after running and doing soft tissue mobility work with a foam roller, lacrosse ball, or massage gun.
Examples of hip mobility exercises for runners include the following:
- Frankenstein walks
- Hip circles
- Donkey kicks
- Hip swings
- Side leg raises
- Butterfly stretch
- Hip flexor stretch
- Frog stretch
- Fire hydrants
- Agility ladder drills
- Glute bridges
- Straight leg raise
As you can see, there are many preventative measures you can take to help prevent hip pain after running. If you do, however, feel pain, it is important to seek professional help to find the root of the problem and a plan of action to get better quickly!
