Muscle Soreness vs Injury: How to Tell
Every lifter faces this question: is this normal soreness I can train through, or a real injury I should rest? Here’s how to tell them apart.
Normal soreness (DOMS)
- A dull, general ache across the whole muscle.
- Shows up 12–48 hours after training (DOMS).
- Eases with light movement and fades in a few days.
- Both sides usually feel similar.
Warning signs of injury
- Sharp, stabbing or localised pain (one specific spot).
- Pain during a movement, or a sudden "pop."
- Swelling, bruising, or a joint that feels unstable.
- Pain that worsens or lingers well beyond a few days.
If it looks like injury, stop, rest, and see a professional — don’t "push through." See our disclaimer.
Dull, both-sides, next-day ache = soreness. Sharp, one-spot, during-movement pain = possible injury — rest and get it checked.
Quick answers
Can I work out with sore muscles?
Usually yes — light training or working other muscles is fine. Sharp or localised pain, though, means stop and assess.
How do I know if I pulled a muscle?
A sudden sharp pain, a "pop," swelling or weakness in one spot suggests a strain — rest it and seek advice if it persists.
