The soreness that arrives two days after training, and the cramp that stops you mid-session. Usually normal, occasionally not.
What it typically feels like
Soreness peaking 24 to 72 hours after a session, not during it
Stiffness and tenderness across a whole muscle group, not one point
Sudden involuntary cramping, often calf or hamstring
Muscles that feel permanently tight despite stretching
Delayed onset muscle soreness
DOMS is the ache that turns up a day or two after unfamiliar training — new
exercise, more weight, or the return after time off. It peaks somewhere between
24 and 72 hours, and it is caused by microscopic damage to muscle fibres as they
adapt.
It is a normal training response, not an injury. It is also a poor measure of
how good a session was — the absence of soreness does not mean the session was
wasted.
How to tell it from an injury: DOMS is spread across a whole muscle group,
affects both sides roughly equally, and eases as you move. An injury is usually
one specific point, on one side, and gets worse with use.
Massage will not make DOMS vanish, but it genuinely eases the stiffness and gets
you moving comfortably sooner.
Cramp
Sudden, involuntary and unmistakable. Most often the calf or hamstring, often
during or after hard effort, and often at night.
Contributing factors are usually some combination of fatigue, dehydration,
electrolyte loss, and a muscle that was already tight before you started. That
last one is where treatment helps — muscles carrying trigger points and chronic
tightness cramp far more readily than healthy ones.
Frequent cramping without an obvious cause is worth mentioning to your GP.
It is occasionally a sign of something needing investigation, particularly if it
is new, worsening, or accompanied by weakness.
What treatment involves
Regular soft tissue work as maintenance rather than repair — keeping tissue
quality good so that it recovers faster and cramps less. This is the most
common reason people book in regularly rather than only when something breaks.
What is actually in the all over, or not sure
Some things do not belong to one region. Soreness after training, cramp, and the general tightness that comes from doing a lot or from doing very little.
Muscle and connective tissue
Muscle is wrapped, bundled and linked by fascia, and that wrapping is continuous through the body. It is why tightness in one area can pull somewhere that seems unrelated.
Delayed onset muscle soreness
The ache that peaks a day or two after unfamiliar training. It follows the eccentric part of a movement — the lowering — and it is a normal adaptation rather than an injury.
Trigger points
Tight, tender bands within a muscle that refer pain elsewhere in a predictable pattern. The referral is the reason so many problems get treated in the wrong place.
Why it goes wrong
Pain that moves around, or that turns up in several places at once, usually says more about overall load, sleep and recovery than about any single structure. It is still worth assessing, because the pattern itself is informative — but it changes what treatment is aiming at.
This page describes what is common, not what you have. The only way
to know is to have it assessed — and your first session includes a
full assessment, so you leave knowing what is actually going on.
