When to Rest and When to Rehab: Understanding Muscle Soreness vs. Injury

LPT Blog May 105351258 L 1920

Getting back into a workout routine or increasing your physical activity can feel empowering—but that post-workout soreness the next day? Not always as fun. The tricky part is knowing whether you’re simply sore or experiencing the early signs of an injury.

At Lafayette Physical Therapy, we often meet people who aren’t sure when to rest, when to keep going, or when it’s time to seek professional care. It’s a common concern—and an important one. Learning how to listen to your body can make all the difference in preventing long-term issues and maintaining a healthy, active lifestyle.

What Is Muscle Soreness?

Muscle soreness, especially delayed onset muscle soreness, is a totally normal part of physical activity. It usually shows up 12–48 hours after exercise and is caused by tiny microtears in your muscle fibers. These microtears lead to inflammation, which then triggers the aching, tight feeling we recognize as soreness.

You’ll often feel this kind of soreness after:

  • Trying a new workout
  • Increasing your intensity or weight
    Using muscles in ways they’re not used to

The key thing to remember is that muscle soreness is temporary, and while it can be uncomfortable, it usually resolves on its own with rest, hydration, and gentle movement. At Lafayette PT, we often reassure clients that soreness can possibly be a sign of progress—as long as it stays within reason.

Is It “Just Soreness”?

While everyone experiences soreness differently, there are a few general signs that what you’re feeling is normal:

  • Aching or tightness that’s mild to moderate
  • Discomfort that peaks in 1–2 days and then fades
  • Pain that’s evenly distributed across both sides of the body
  • Movement may feel stiff, but not impossible

If this sounds like what you’re experiencing, rest assured: some light stretching, gentle movement (like walking or yoga), and plenty of water can help ease the discomfort.

When It Might Be an Injury

So when should you worry that it’s more than just post-workout soreness? There are a few red flags to watch for that may suggest you’re dealing with an injury rather than normal muscle fatigue:

  • Sharp or stabbing pain, especially if it’s isolated to one area
  • Pain that worsens over time, rather than improves
  • Swelling, bruising, or warmth around a joint or muscle
  • Limited range of motion that doesn’t improve with movement
  • Pain that interferes with sleep or daily activities.

If any of these symptoms sound familiar, it might be time to consult a physical therapist. At Lafayette Physical Therapy, we work with patients across Lafayette and surrounding communities to assess discomfort, provide clarity, and create a plan that’s tailored to your body and your goals.

Rest Isn’t Always the Answer

It’s common to assume that the solution to any pain or soreness is to simply stop moving—but that’s not always the case. 

Prolonged inactivity can actually delay recovery, especially in the case of stiffness or mild muscle strain. In many cases, gentle movement, guided stretching, and specific exercises can accelerate healing and prevent the issue from becoming chronic.

If you’re unsure about what level of activity is safe, that’s where working with a licensed physical therapist can be especially helpful. At Lafayette PT, we take the guesswork out by designing customized recovery plans that strike the right balance between rest and movement.

Your Body’s Talking—Here’s How We Listen

When you’re caught between wanting to stay active and not wanting to make things worse, physical therapy offers a valuable middle ground. 

We don’t just help after major injuries—we’re here for those in-between moments, too. That lingering ache that won’t go away? The stiffness that keeps flaring up every time you stretch? These are the signs your body may need a little extra support.

At Lafayette Physical Therapy, our experienced team works closely with clients to:

  • Evaluate pain and determine its cause
  • Identify muscle imbalances or movement issues
  • Create a step-by-step plan for recovery and strengthening
  • Help you return to your routine with confidence

It’s not about stopping activity altogether—it’s about adapting and supporting your body in the right way.

When to Seek Professional Support

You don’t need to be in severe pain to benefit from physical therapy. If you’ve been experiencing discomfort for more than a few days, or your body doesn’t seem to be bouncing back the way it used to, we encourage you to check in.

Other signs it might be time to book an appointment:

  • Recurring pain after workouts
  • Trouble with mobility or balance
  • A recent increase in activity that left you feeling worse, not better
  • Feeling unsure if you’re doing the right stretches or exercises

Even one session can offer valuable insight into your body’s mechanics and how to adjust your routine to better support long-term health.

You Don’t Have to Tough It Out

It’s easy to feel like you should “just push through” or that pain is a sign of weakness—but that mindset often leads to longer recovery times and bigger setbacks. 

Pain is your body’s way of signaling something isn’t quite right. Learning to respond with care instead of ignoring it can help you stay active, strong, and confident for years to come.

At Lafayette Physical Therapy, we create an environment that’s informative, respectful, and focused on meeting you where you’re at. Whether you’re recovering from a tough workout or healing from a strain, we’re here to support your journey—without judgment or pressure.
