What to notice
Describe the trigger precisely: reaching the front court, pushing back, stairs afterwards or a particular landing. This helps a clinician or coach understand the task without assuming a diagnosis.
Practical next steps
- Reduce repeated deep-lunge drills if they provoke pain.
- Have your coach review approach steps and recovery footwork.
- Track court practice alongside running and leg-strength sessions.
When to get help
Seek urgent assessment for a badly swollen or deformed knee, inability to bear weight, locking or giving way. A hot, red knee with fever also needs urgent care.
