Flare-up vs reinjury: the decision framework
A flare-up is a sensitivity spike. A reinjury is a new tissue problem. The responses are different—this page shows you how to choose the right one.
Flare-up patterns
- Triggered by stress, poor sleep, too much volume
- Settles within days when variables are reduced
- Function returns quickly
Reinjury patterns
- Clear incident
- Progressive worsening
- New functional loss or instability
Quick answers
- What’s the first move in a flare-up?
Reduce variables: keep movement, lower volume, avoid novel exercises, and stabilise sleep and stress. - Should I ice or heat?
Use whichever helps you move comfortably. The bigger lever is load and consistency. - When do I seek help?
If symptoms worsen rapidly, you lose function, or you’re unsure, get clinical guidance.
What happens next
- Clarify your goal + constraints (time, equipment, pain history, schedule).
- Baseline: posture + movement screen, and a plan you can actually follow.
- Progress: weekly check-ins, technique coaching, and load management.
