Why Pain During Exercise Is Okay

← Back to Blog

One of the most common questions I get as a Doctor of Physical Therapy is: "Should I be exercising if I'm in pain?" The answer might surprise you — in many cases, yes. Understanding the difference between pain that's safe to push through and pain that signals damage is one of the most important things you can learn.

Not All Pain is Created Equal

Pain is your nervous system's way of communicating — but it doesn't always mean tissue damage is occurring. You can have significant structural findings on an MRI and feel no pain. Conversely, you can be in significant pain with no identifiable structural cause.

The Pain Scale: A Useful Guide

• 0-3/10: Generally safe to continue — mild discomfort expected with loading deconditioned tissues
• 4-5/10: Proceed with caution — modify the exercise, reduce load or range of motion
• 6+/10: Stop and reassess — this level warrants attention and modification

Warning Signs to Stop

• Sharp, shooting, or stabbing pain
• Pain that worsens with each repetition
• Swelling, instability, or giving way
• Numbness, tingling, or radiating symptoms
• Pain significantly worse the day after exercise

The Danger of Complete Rest

Avoiding all movement when in pain is often counterproductive. Tissues heal better with controlled loading. Rest leads to deconditioning, which often makes pain worse over time. The goal isn't to avoid pain — it's to move smartly within a tolerable range while progressively building capacity.
