You finish a hard workout and wake up the next morning feeling stiff, tight, and sore.

Is that normal?

Or did you actually hurt yourself?

Knowing the difference between muscle soreness and injury pain can be difficult. Many athletes and active adults push through discomfort because they assume pain is simply part of getting stronger. Others may stop exercising every time they feel sore, even when the discomfort is a normal response to a new or challenging workout.

Understanding the difference between pain vs. soreness can help you make better decisions about training, recovery, and when to seek professional advice.

While mild muscle soreness can be a normal part of exercise, certain types of pain may indicate that something needs attention.

What Is Muscle Soreness?

Muscle soreness after exercise is often referred to as delayed onset muscle soreness, or DOMS.

DOMS commonly develops after you perform an unfamiliar activity or increase the intensity or volume of your workout.

You may notice soreness after:

• Starting a new workout program

• Increasing your weights

• Running farther than usual

• Trying a new sport

• Adding more repetitions

• Performing exercises your body isn’t accustomed to

• Returning to exercise after a break

Soreness often develops several hours after exercise and can become more noticeable the following day.

You might feel:

• General muscle tenderness

• Stiffness

• Mild discomfort when moving

• Temporary weakness

• Tightness in the muscles

• Sensitivity when the muscles are touched

In many cases, normal workout soreness gradually improves as your body recovers.

What Does Injury Pain Feel Like?

Injury pain can feel different from normal post-workout soreness.

There isn’t one specific type of pain that automatically means you’ve been injured, but certain characteristics deserve more attention.

Potential warning signs include:

• Sudden or sharp pain

• Pain that occurs during a specific movement

• Pain that causes you to change how you move

• Significant swelling

• Bruising

• Loss of strength

• Loss of range of motion

• Joint instability

• Pain that continues or worsens instead of improving

• Pain that repeatedly returns during activity

For example, feeling general muscle soreness after increasing your squat volume may be expected.

Feeling a sudden sharp pain in your knee during a squat is a different situation.

The context matters.

Pain vs. Soreness: What’s the Difference?

One of the easiest ways to think about pain vs soreness is to consider when it occurs, where you feel it, and how it affects your movement.

This isn’t a diagnostic checklist. Different injuries can present differently, and soreness can sometimes be significant.

If you’re unsure about your symptoms, an individualized assessment can provide more useful information than trying to self-diagnose based on pain alone.

When Is It Normal to Be Sore After a Workout?

Some soreness after exercise can be completely normal.

Your muscles adapt when they are exposed to physical demands that are greater than what they’re accustomed to.

For example, if you’ve never performed a particular strength exercise before, your body may experience soreness afterward.

The same can happen when you:

• Increase your running distance

• Add resistance training

• Change your workout routine

• Increase workout intensity

• Return to training after time away

The key is to pay attention to the overall pattern.

If the soreness is gradually improving and you’re able to move normally, it may simply be part of your body’s adaptation to training.

However, severe or persistent symptoms shouldn’t automatically be dismissed as “just soreness.”

When Should You Stop Exercising?

One of the biggest questions athletes ask is:

“Should I push through the pain?”

The answer depends on what you’re experiencing.

Mild, familiar muscle soreness isn’t necessarily a reason to stop all physical activity.

However, you should be more cautious if exercise produces:

• Sharp or sudden pain

• Increasing pain during a movement

• Significant swelling

• A feeling of instability

• Sudden loss of strength

• Loss of normal movement

• Pain that changes your technique

• Pain that becomes progressively worse during a workout

If you have to significantly change how you perform an exercise to avoid pain, that’s a sign to stop and reassess rather than simply pushing harder.

The Problem With “No Pain, No Gain”

You’ve probably heard the phrase:

“No pain, no gain.”

While challenging yourself is an important part of improving fitness and performance, pain isn’t a requirement for progress.

Exercise can be difficult without being harmful.

There’s a difference between:

Training discomfort

and

Potential injury pain.

A challenging workout may leave your muscles tired or uncomfortable.

An injury may produce symptoms that affect your movement, strength, or ability to perform an activity normally.

Learning to recognize this difference can help you train more intelligently.

What About Pain During Running?

Runners frequently encounter the question of whether they should continue running when something starts to hurt.

Some discomfort can occur when your body adapts to changes in training.

But persistent or worsening pain shouldn’t automatically be ignored.

Pay attention if:

• Pain appears consistently at a specific point during your run

• The pain gets worse as you continue

• You start limping

• Your running form changes

• Pain remains after the run

• Your symptoms are getting worse from session to session

• The same pain repeatedly returns

A recurring running injury may be related to training volume, recovery, strength, mobility, biomechanics, or other factors.

A sports physiotherapy assessment can help identify potential contributing factors and determine an appropriate plan for returning to running.

What About Soreness After Strength Training?

Strength training commonly produces muscle soreness, particularly when you introduce new exercises or increase training volume.

For example, after a challenging leg workout, you might experience soreness in your:

• Quadriceps

• Hamstrings

• Glutes

• Calves

This doesn’t necessarily mean you’ve damaged yourself or need to stop exercising altogether.

However, severe pain, significant swelling, major weakness, or pain concentrated around a joint deserves more attention.

You should also be cautious if pain changes your technique or prevents you from performing normal movements.

Why Does Soreness Happen After Exercise?

When your body encounters a physical demand it isn’t accustomed to, it has to adapt.

Your muscles and other tissues respond to training by undergoing a variety of physiological changes.

This is one reason why a new workout can make you feel considerably more sore than your usual routine.

Over time, consistent and appropriately progressed training can help your body become more accustomed to the workload.

That’s why gradual progression is an important part of exercise programming and sports injury prevention.

How Can You Reduce Excessive Workout Soreness?

You don’t need to avoid soreness completely.

Instead, focus on managing your training load and giving your body enough time to adapt.

Increase Training Gradually

Avoid making dramatic increases in weight, mileage, duration, or intensity.

Include Recovery Days

Your body needs time to adapt to training.

Warm Up Before Exercise

A warm-up can help prepare you for the movements and intensity of your workout.

Maintain Consistent Training

Large gaps followed by sudden intense workouts can increase the physical demands placed on your body.

Prioritize Sleep and Recovery

Recovery is an important part of training—not time wasted between workouts.

Don’t Ignore Persistent Pain

If something repeatedly hurts during training, don’t simply assume you need to “push through.”

What Should You Do If You’re Not Sure Whether You’re Injured?

If you’re struggling to determine whether you’re experiencing normal soreness or a potential injury, consider the bigger picture.

Ask yourself:

Did the pain happen suddenly?

A sudden pain during a particular movement deserves more attention.

Is the pain getting worse?

Symptoms that progressively worsen may require assessment.

Has my movement changed?

Limping, avoiding certain movements, or changing exercise technique can be important clues.

Is there swelling or bruising?

These symptoms may warrant professional assessment.

Does the same pain keep coming back?

Recurring pain shouldn’t simply be ignored.

Can I perform my normal activities?

A significant loss of function is a reason to seek professional guidance.

When in doubt, getting assessed can help you understand what you’re dealing with instead of repeatedly guessing.

How Can Physiotherapy Help With Sports Injuries?

A physiotherapist can assess more than just the location where you feel pain.

Depending on your situation, an assessment may consider:

• Strength

• Mobility

• Joint movement

• Balance

• Coordination

• Movement patterns

• Training history

• Previous injuries

• Exercise technique

• Sport-specific demands

This can help identify factors that may be contributing to your symptoms.

Treatment and rehabilitation may include:

• Exercise therapy

• Strength training

• Mobility work

• Manual therapy

• Movement retraining

• Education

• Load management

• Return-to-sport progression

The goal isn’t simply to make you feel better temporarily.

For many sports injuries, rehabilitation focuses on helping you restore the capacity needed to return to your normal activities.

Pain Doesn’t Always Mean You Have to Stop Moving

One of the biggest misconceptions about sports injuries is that the only solution is complete rest.

Depending on the injury, complete inactivity may not always be necessary or helpful.

A physiotherapist can help determine what types and levels of activity may be appropriate while you’re recovering.

For example, you may need to temporarily modify:

• Exercise intensity

• Running distance

• Training frequency

• Weight lifted

• Range of motion

• Certain exercises

• Sport-specific activities

Instead of thinking:

“I can’t exercise.”

The better question may be:

“How can I safely modify my activity while I recover?”

When Should You See a Physiotherapist?

Consider speaking with a physiotherapist if:

• Your pain keeps returning

• Your symptoms are affecting your workouts

• You’re unable to perform movements normally

• Your pain is getting worse

• You’re unsure whether you should continue training

• You recently sustained a sports injury

• You’re preparing to return to sport after an injury

• You want help preventing another injury

• Your performance has changed because of pain

You don’t always need to wait until an injury becomes severe.

Early assessment can help you better understand the problem and determine what steps may be appropriate.

Frequently Asked Questions About Pain vs. Soreness

Is muscle soreness after exercise normal?

Mild muscle soreness can be a normal response to a new or more challenging workout. However, severe, persistent, or unusual symptoms should not automatically be considered normal soreness.

How can I tell if I’m injured or just sore?

Consider when the symptoms started, where they occur, whether they affect movement, and whether they’re improving. Sudden, sharp, localized, or progressively worsening pain may warrant professional assessment.

Should I work out if I’m sore?

It depends on the severity and type of soreness. Mild muscle soreness doesn’t necessarily mean you need to stop all activity, but you may need to modify your training. Significant pain or symptoms that alter your movement should be taken more seriously.

Is it okay to exercise through pain?

Not all pain means the same thing. Pushing through sharp, worsening, or function-limiting pain is generally not a good strategy. If you’re uncertain, consider getting an individualized assessment.

How long should muscle soreness last?

Workout soreness often improves as your body recovers, but the duration can vary depending on the activity, training status, and individual factors. Persistent or worsening symptoms deserve further attention.

Can physiotherapy help with recurring sports injuries?

Yes. Physiotherapy can assess factors such as strength, mobility, movement, training load, and sport-specific demands and can help develop an individualized rehabilitation and return-to-activity plan.

The Bottom Line: Learn to Listen to Your Body

Being sore after a workout doesn’t automatically mean you’ve injured yourself.

At the same time, not every painful sensation should be ignored.

Understanding the difference between pain vs. soreness can help you make smarter decisions about your training and recovery.

If discomfort is mild and improving, your body may simply be adapting to a new physical demand.

If pain is sharp, persistent, worsening, repeatedly returning, or affecting how you move, it’s worth taking a closer look.

Your body doesn’t always need you to stop moving.

Sometimes it needs you to change how you’re moving, adjust your training load, and give it the right support to recover.
