Running injury
What causes lower-leg tightness during running that improves after stopping?
Doctor’s answer
Pain and tightness that repeatedly begin at a similar running distance or time and gradually ease after stopping may indicate chronic exertional compartment syndrome. Numbness or weakness can also occur. Assessment should exclude a stress fracture, vascular disorder, and nerve entrapment.

Could pain on the outside of the knee while running be iliotibial band syndrome?
Yes. Iliotibial band syndrome typically causes localised lateral-knee pain during running and may be more noticeable downhill, after a sudden mileage increase, or with repeated knee bending. Management includes temporarily reducing running load, improving hip strength, and adjusting training and running mechanics.
Can insufficient sleep increase sports injury risk and slow recovery?
Insufficient sleep can reduce reaction speed, attention, and movement control and can interfere with muscle repair, pain regulation, and recovery after training. Athletes should keep a regular schedule and allow enough sleep for their training load. Persistent insomnia, marked daytime sleepiness, or snoring with pauses in breathing warrants assessment.
Should athletes use static stretching or a dynamic warm-up before exercise?
Begin with 5 to 10 minutes of low-intensity activity, followed by a sport-specific dynamic warm-up such as high knees, lunges, leg swings, and progressive accelerations. Longer static stretches are generally better placed after training or in a separate flexibility session.
