IT Band Pain in Runners: Why the Outside of the Knee Can Hurt During Training post

If the outside of your knee starts hurting at the same point in every run, especially after a few miles, on hills, or when your mileage increases, iliotibial (IT) band irritation may be the cause. IT band pain in runners usually causes a sharp or nagging ache on the outside of the knee during repeated motion, especially when training load increases faster than the body can adapt.

The iliotibial band runs along the outside of the thigh, from the hip to just below the knee. When the tissue near the outside of the knee becomes irritated, runners may also feel tightness along the side of the leg or a popping sensation near the joint.

At Medical & Sports Massage in Sandy Springs, I have treated IT band pain in runners for more than 12 years.

What IT band pain feels like in runners

IT band pain in runners usually feels like a sharp, aching, or burning pain on the outside of the knee. It often gets worse the longer you run and may start at a predictable point in your route or workout. Many runners notice that the pain settles after they stop, then returns when they run again.

Some runners also feel tightness along the outer thigh or a clicking or popping sensation near the knee. These symptoms can become more noticeable on hills, longer runs, or during training blocks with higher mileage.

Why the outside of the knee hurts

Medical sources such as Johns Hopkins Medicine, Cleveland Clinic, and Hospital for Special Surgery describe IT band syndrome as an overuse injury that commonly affects runners and cyclists. It usually causes pain on the outer side of the knee, where repeated bending of the knee during running can irritate tissue near the lower end of the iliotibial band.

Every running stride repeats that motion. Higher mileage, downhill running, uneven roads, harder surfaces, worn shoes, and sudden changes in training can all add stress. Published research on runners points to similar training patterns, including higher weekly mileage and downhill running, as common factors in IT band syndrome.

Should runners foam roll IT band pain?

A lot of runners reach for a foam roller when the outside of the knee starts to hurt. Foam rolling may help some runners feel looser, but aggressive rolling directly over an irritated IT band can worsen symptoms. When the area is painful or inflamed, I am cautious with hard pressure along the outside of the thigh.

At Medical & Sports Massage, I usually start by assessing the surrounding tissue, hips, and glutes rather than forcing pressure into the most painful spot. If foam rolling makes the pain sharper instead of easier, that is a sign to back off and have someone look at the full pattern.

When to consider sports massage, physical therapy, or medical care

Sports massage can help address muscle tension and movement patterns that may contribute to IT band irritation. It can also pair well with the strength work a physical therapist may prescribe.

Massage is not a cure for IT band syndrome, and I am honest with runners about that. If the pain is sharp, keeps returning, changes how you run, or stops you from running, it is time to see a physician or physical therapist for an evaluation. Massage works best as part of a plan that includes medical care, strength work, recovery, and smart training changes.

How sports massage can help runners with IT band pain

The first step is understanding what you are training for and how the pain behaves. A runner preparing for the Peachtree Road Race, a fall half marathon, a marathon, or a trail race may need a different approach than someone easing back into mileage after time off.

In a session, I look at:

  • Where the knee pain starts.

  • How far into the run it begins.

  • Whether hills or downhill running make it worse.

  • Whether the outside of the thigh feels tight.

  • Whether the hips or glutes feel restricted.

  • What race, mileage, or training goal is coming up.

From there, I tailor the session to your symptoms, movement limits, and goal. I usually focus on the hips, glutes, and tissue around the IT band rather than grinding on the sore spot near the knee.

For a broader look at race-season training load, I also wrote about this in my guide to sports massage for Peachtree Road Race and marathon training.

Common questions runners ask me

What does IT band pain feel like in runners?
Most often a sharp or burning ache on the outside of the knee that builds the longer you run and settles when you stop. Some runners also feel tightness up the outside of the leg or a popping near the knee.
Why does the outside of my knee hurt when I run?
Repeated bending and straightening of the knee can irritate the IT band where it crosses the joint. Mileage jumps, hills, worn shoes, and hip or glute weakness can each add to it.
Can sports massage help IT band pain?
It can help with muscle tension and movement patterns associated with the irritation, and it works well alongside physical therapy. It is not a cure, so I treat it as one part of a plan that includes medical care when needed.
Should I foam roll a painful IT band?
Be careful. Rolling hard on a band that is already irritated can worsen the pain. I usually work the hips, glutes, and surrounding tissue first and go gently near the knee.
Why does my knee pop when I run?
T band irritation can sometimes feel like clicking or popping near the knee. If the popping comes with pain that keeps returning, it is worth having it looked at.
