Workout Pain You Should Never Ignore

“No pain, no gain” sounds tough, but it’s one of the most misleading lines in fitness. Some discomfort is part of getting stronger: burning muscles near the end of a set, or soreness a day or two after a hard session. Other pain is your body telling you something is wrong, and pushing through it can turn a small problem into a long layoff.

Here’s the workout pain you should never ignore, how to tell it apart from normal soreness, and what to do next.

Good Pain vs. Bad Pain: The Quick Version

• Usually normal: a muscle burn during the set that fades when you rest, and general soreness 1 to 2 days later that eases as you move
• Worth stopping for: sharp or stabbing pain, pain in one specific spot, pain that builds as you keep going, swelling, a painful pop, or pain that changes how you move

Pain Accompanied By Swelling

Pain with swelling usually means something underneath is irritated or injured, such as a sprain or a strain. If you notice it during a workout, stop and pay attention to the area instead of finishing the set.

A mild injury may settle in a few days with rest and gentle movement. If the swelling isn’t going down after a few days, or the pain is getting worse, get it checked.

Pain Accompanied By A ‘Pop’

Clicks and pops during exercise are common, especially as we get older, and on their own they usually don’t mean anything serious. Your knees, hips and shoulders may make noise without any problem at all.

A pop that comes with pain is different. It can mean a tear or a joint that has partially slipped out of place, and it will usually get worse if you try to push through it. Stop, and have it looked at.

Acute Pain

Sudden, sharp or stabbing pain during a workout is not normal training discomfort. It can point to a muscle or tendon tear, a joint injury or a bone problem. Trust your gut. Stop the exercise and get it checked before you try it again.

Pain Higher Than 5 On A Scale Of 1 To 10

Rating your pain from 0 to 10 is a simple way to make better decisions. Mild discomfort that stays low and settles quickly is usually fine to work with. If your pain climbs above about 5 out of 10, that’s a sign to stop, not a sign that you’re working hard.

Also check how you feel the next day. Pain that is clearly worse the morning after a workout means the dose was too much, even if it felt manageable at the time.

Pain That Gets Worse The More You Workout

Some stiffness eases as you warm up, and that’s often fine. But if pain keeps building with every set or every mile, you’re putting more stress on an area that can’t handle it right now. Stop and change the plan instead of hoping it will loosen up.

Pain In Just One Area Of Your Body

Normal soreness after a good workout is spread out across the muscles you trained. Pain that is localized, in one specific spot such as the front of the knee, the outside of the elbow or one side of the lower back, is more likely to be an irritated tendon, joint or muscle. If it shows up with the same exercise every time, or gets worse as you train, it’s worth an assessment. Our guide to the most common sports injuries covers what these often turn out to be.

When to Get Checked Right Away

• You can’t bear weight: or you can’t move the joint normally after an injury
• Visible deformity: or rapid, large swelling or bruising
• Numbness, tingling or weakness: that spreads down an arm or leg
• Chest pain, shortness of breath or dizziness: stop and call 911
• Dark urine with severe muscle pain: after a very hard session, which needs urgent medical care

What To Do Next

1. Stop the exercise that hurts: pain is information. Listen to it.
2. Keep moving what doesn’t hurt: you can usually train other areas while the sore one settles. See how to stay fit while recovering from an injury.
3. Calm it down: ice or heat and gentle, pain-free movement can ease symptoms in the first few days.
4. Don’t rely on painkillers to train: masking pain lets the problem keep building.
5. Get it assessed if it lasts: if pain hasn’t improved in a few days, or it keeps coming back when you return to training, find out why.

Most workout injuries come from a cause you can fix, such as a stiff joint, a weak link or a training load that jumped too fast. Our guide to why sports injuries happen explains the most common ones.
