Symptoms of IT band syndrome may vary slightly from person to person in intensity and how they appear.
Some symptoms include:
pain when running or doing other activities involving the outside of the knee
a clicking sensation where the band rubs against the knee
lingering pain after exercise
the knee is tender to touch
tenderness in buttocks
redness and warmth around the knee, especially the outer aspect
Symptoms typically begin a short time after starting the physical activity.
The most common symptom of IT band syndrome is pain on the outside of the knee that gets worse if the person continues the activity causing the pain.
As a person continues to run or participate in a similar activity, the IT band will continue to rub against the outside of the knee, leading to swelling and severe pain.
