What Lower Back Feels Like
Running-related lower back pain is usually mechanical — muscle, joint, or disc irritation from poor core control, repetitive impact, and accumulated training load. True structural causes (stress reaction of the pars, disc herniation) exist but are less common.
- Tightness after long runs
- Morning stiffness that eases with movement
- Discomfort sitting after sessions
- Pain that worsens with prolonged standing or sitting
Early Warning Signs
Catching lower back at this stage is the difference between a week of reduced training and a multi-week shutdown.
- Tightness after long runs
- Stiffness in the morning
- Discomfort sitting after sessions
When to Stop and See a Clinician
- Pain radiating down a leg
