Where nagging
injuries come from

This one has no moment attached to it. Nothing happened. It was just there one day, and it never quite went away.

Everything else you can get hurt by announces itself. Something goes wrong, you know about it, and there's a date you could put on it.

This one doesn't work like that — which is why it catches people who are otherwise careful.

It has a name and a mechanism: accumulation. And because it never hurts enough at any single moment to demand attention, it's the kind of injury people are most likely to let run for months.

Nothing dramatic ever occurs. The same joint just takes a small amount of torque, over and over, week after week — and one day you notice something has been complaining for eight months and you can't say when it started. Those are the nagging problems that eventually turn into a surgery.

There was never a moment where a tap would have saved you. That's what makes it different from everything else on this page.

It isn't one thing doing it. It's the same small amount of torque, on the same joint, hundreds or thousands of times.

People assume the culprit must be submissions. Usually it isn't.

Simple base positions rarely do it. Side control, mount, closed guard put weight on you — sometimes a great deal of it — but they don't twist anything.

It's the nuanced positions that do. The ones that need a limb to sit at an angle it doesn't naturally want and hold it there under pressure. Nothing about that hurts in the moment; it's well inside what the joint can take. But it isn't neutral, and doing it a thousand times isn't the same as doing it once.

Leg entanglements are the clearest example. A lot of those positions put a knee under slow rotational load as a matter of course — not as a submission attempt, just as the price of being there. Repeat that a few times a session for a year and you have something that never quite stops.

And your own habits do it. Not escaping armbars — escaping them a particular way. If your escape twists your shoulder out under the pressure rather than moving your body around it, that's a rotation it doesn't want to make, under load, for years.

It's rotation under pressure that does this. Twisting a joint in a direction it doesn't naturally go, while somebody's weight is on it.

Hold onto that, because it lets you spot the ones nobody has named for you. Weight alone is fine. A heavy person on your chest is unpleasant and isn't damaging anything. It's when the joint is being turned at the same time that you start paying.

So don't look for what hurts. Look for where you routinely twist something while it's loaded — the escape that corkscrews a shoulder free, the pass that angles your knee while your weight goes through it, the way you turn your neck instead of moving your hips.

Here's the part that matters, because it changes who's responsible for this.

None of these are silent. You get a signal every single time — it's just small. A slight twinge when you twist out of an armbar the way you always do. A little something in the shoulder during a particular pass. Not enough to stop for. Not enough to mention.

So you dismiss it. Everybody dismisses it. And that dismissal is the actual culprit — not the position, not the technique.

That small twinge isn't a minor annoyance. It's the same warning system as everything else on this page, running at low volume.

It's telling you exactly what a sharp pain would tell you: this structure is being loaded in a direction it doesn't like. The only difference is that it's quiet enough to train through, so you do, and then you do it again next week.

Accumulation isn't something that happens to you without notice. It's something you were told about a hundred times, softly, and carried on regardless.

The instruction is simple and almost nobody follows it: when you feel a small, specific twinge in the same movement more than once, that's the moment to act. Not when it gets worse. Then.

Acting doesn't mean stopping. It means changing something — the angle you're escaping at, the way you're passing, which side you do it from, or whether you take that position at all. Anything that stops the same joint taking the same load in the same direction.

And if you can't work out what's causing it, that's a good question for your instructor. Something in my shoulder every time I do this escape — can you look at how I'm doing it? Ten seconds of their time, and it's the kind of question that's worth years.

The diagnostic is easy: something mildly annoying for more than a couple of weeks that you can't trace to a single incident. That's accumulation, and it will keep going until something about the position changes.

Twenty years of watching people train and it's the same short list, over and over.

Fingers, from gripping — the most common of the lot and the one people write off entirely. Elbows and shoulders. Ankles. Really any joint loaded at an angle often enough. And cauliflower ear, which isn't a joint but belongs here anyway — once you have it, it reactivates.

None of those stops you in a single dramatic moment. They just accumulate until something has been sore for months.

Everybody gets things that nag, so working around them isn't a special case — it's a normal part of training that nobody teaches. The default advice is rest, and that's how people drift off the mat.

The way you've been training is what produced the injury. Carrying on the same way and expecting it to settle isn't realistic.

So: drill more, roll less, and lower your intensity across the board — not just around the sore thing, the whole session. Very little of what you actually need to learn requires going hard.

I tore my MCL a few years back — around seventy-five percent, so not complete but not nothing. And I wanted to keep training.

So I worked out what I could do without that leg. For months I trained almost entirely from the bottom of side control with the left leg straight and unused. No guard, no pushing anybody away, and I couldn't afford to let anyone grab my pants. So I gave up side control, let people mount me, and got very good at surviving from underneath — training I'd never have chosen otherwise.

Give away the positions you can't defend, and get good at the ones you're left with.

That's the whole method. Work out which movements aggravate it, take those out of your game for a while, and accept a much narrower version of training. You'll still be on the mat and still improving, and the thing gets a chance to settle.

Most people never consider it because it doesn't look like normal training. It beats the alternative, which is stopping.

Almost every injury I've seen on a mat can be worked around. Ribs can't.

They're your core, involved in everything, and almost any amount of bodyweight in the wrong place sets them off again. There's no clever way around ribs.

So take a month — but don't disappear. Turn up anyway, do whatever light drilling you can, and watch. You'll notice things from the side of the mat you'd never notice while you're in it, and staying in the room is what stops a month becoming the end of it.

You can't reliably spot an injury on somebody else. Braces tell you little — plenty of people wear a knee brace because they're forty-five. And pain thresholds vary too much to judge by watching.

So it's on the injured person to say so. Before the round, plainly: my right arm is jacked up, mind being careful with it. And when somebody tells you that, they're trusting you. Don't go hunting the thing they just named.

And if you're the injured one — don't take advantage of it either.

Somebody asks their partner to go light because of an injury, then spends the round trying to take their head off, using the fact that the other person is being careful.

That's a fast way to have nobody willing to roll with you — and it tends to explain how they got injured in the first place. The deal runs both ways or it isn't a deal.

One line that isn't optional: if something is getting worse week over week, or it hurts when you aren't training, that's not something to work around. Go and get it looked at by somebody qualified.

The small pain is the warning. Ignoring it is the injury.

And if you want the rest of it — how to tell pain from pressure in the first place, and what to do about the fast kind — that's pain and pressure.
