Why Does Delayed Onset Muscle Soreness Happen?

DOMS comes from tiny micro-tears in your muscle fibres that occur when you challenge your muscles in new or intense ways. These tears are necessary for muscle growth and adaptation. Your body repairs the damage, making the muscle stronger and better prepared for next time.

If it helps, picture the Hulk bursting out of his clothes as he grows bigger (and greener). Your muscles are breaking down to rebuild stronger “bridges” for the future. It’s not damage to fear—it’s damage with purpose.

What DOMS Is Not

• Not a lactic acid build-up. That burning sensation you feel during exercise when your muscles fatigue is different. DOMS appears later, after recovery has already begun.
• Not usually a muscle strain. Strains tend to cause sharp, immediate pain during activity, while DOMS creeps up hours later and peaks the next day.

How to Ease DOMS

Unfortunately, there’s no magic cure for delayed onset muscle soreness—but there are ways to make it more manageable:

• Keep moving. You’ll often notice the stiffness and soreness feels worse after sitting or lying down for a while. Regular movement helps circulate blood and ease the ache.
• Wait it out. DOMS usually peaks 24 hours after exercise and fades within 48–72 hours. It’s uncomfortable, but temporary.
• Stretch, warm up, and cool down. While these won’t stop DOMS completely, they may reduce severity and help you recover faster.

When to Ask for Help

If you’re ever unsure whether your soreness is just DOMS or something more, it’s always worth checking in. A quick call or email to our osteopaths may give you peace of mind and save you from the rabbit hole of Dr Google. Sam and I are at Warrandyte and Templestowe, and we genuinely love helping people understand this stuff.

If pain is persisting, sharper than expected, or limiting your ability to move, book an appointment at Infinity Health and Osteo. We’ll assess what’s going on and guide you through recovery.

DOMS and the Bigger Picture

That post-workout grimace as you climb the stairs isn’t just suffering—it’s a sign of progress. The muscle ache represents hard work, adaptation, and the investment you’re making in your health. The next time you feel it, take a moment to reframe the pain as progress—and maybe even smile through it.
