We've all been there. You're out on a run, mid-hike, or deep into a workout, and something hurts. The question that immediately floods your mind: Should I keep going or should I stop?
In the latest solo episode of The Dual Force, Dr. Paige breaks down a practical, research-backed framework for making that call in real time — what she calls The Four Pain Rules for Activity. And she didn't just pull these from a textbook. She used them herself this week, mid-trail run in Breckenridge, Colorado, after slamming her foot into a root hard enough to jam her ankle and stress her Achilles tendon.
The result? She finished the run — hill sprints included — and made an informed decision instead of a fearful one.
Here's a preview of the four rules covered in the episode.
Rule 1: Pain Intensity — The 3-to-5 Threshold
The research says if your pain is at or below a 3 out of 10, you're generally safe to continue. In practice, Dr. Page extends that to a 5 out of 10 for most people — as long as you understand what that number means for you.
Your 0-to-10 scale is personal. Zero is no pain. Ten is "I need the ER because I've never felt anything like this." Everyone's scale is their own, and what matters is what that number represents to your body — not how it compares to someone else's.
Think of it like traffic lights:
Green (0–5): Keep going, but stay aware.
Yellow (5–7): Modify the activity. Rest, change how you're moving, or scale back.
Red (8–10): Stop. Evaluate. If the pain doesn't ease within a few minutes, call it.
The key follow-up question: How long does the pain linger after you stop? If it eases within a couple of minutes, you're likely okay to continue carefully. If it's still screaming 10–20 minutes later, it's time to stop and get help.
Rule 2: Pain Quality — Sharp vs. Dull
Not all pain is created equal. Dull, warm, spreading pain is typically muscular and often manageable. Sharp, electric, pinpoint pain — especially pain you can locate with a single finger — tends to be more structural and deserves serious attention.
Dr. Paige's trail injury was pinpoint. She knew it was tendinous. She'd been managing tendonitis from a recent speed workout, and this impact forced the joint in the wrong direction, stressing the tendon significantly. She's still feeling it days later — a real-world reminder that quality of pain matters as much as intensity.
Rule 3: The 24-Hour Rule — Load vs. Capacity
How do you feel the day after? If pain lingers past 24 hours — or worse, past 48 — you've exceeded your body's capacity for the load you placed on it. That's not just soreness; that's your body telling you it needs recovery and a scaled-back return.
This is also the perfect time to bring in your care team. Pain that's pinpoint and lasts 24–48 hours is what Dr. Paige would call an injury — not just an ache. And catching it early means a far easier rehabilitation than waiting until it becomes a bigger problem. As she puts it: physical therapists would love to see you before the injury forces you off your feet entirely.
Rule 4: The Symmetry Test — Are You Compensating?
Has your gait changed? Are you limping? Are you moving differently to avoid the pain?
When your body compensates — subconsciously shifting load to muscles and joints that weren't designed for it — you risk compensation injuries. New pain in a new place because you were protecting the original injury. If your movement pattern has changed, that's a signal to stop and get it assessed.
Why This Matters
The Dual Force exists because mental health and physical health aren't strangers. An injury doesn't just limit your body — it affects your mindset, your motivation, and your identity as an athlete or active person. These four rules give you a framework to make informed decisions in the moment, so a minor ache doesn't spiral into a major setback.
As Dr. Paige reminds us: you can use three of the four rules right there on the trail. Check your intensity. Feel the quality. Notice if your movement has changed. That's real-time decision-making that could save your season.
