What Time Does in a Long-Standing Illness

"Nothing was wrong, and then one day I suddenly started to hurt."

It's something people who've been ill for a long time often say. But when you listen closely, in most cases it wasn't "sudden" at all.

What built up little by little over several years simply surfaced one day.

I don't see time as the backdrop of illness. Time is one of the axes that make up the body's environment.

The same stimulus, a different result

Let me start with this fact. The very same stimulus can make the body stronger, or can break it down.

Exercise is like that. Load the muscle and the muscle is damaged. But apply it in moderation and leave time to rest, and it becomes stronger than before. Because the body prepares.

What happens if you apply the same load continuously, with no time to rest? It doesn't get stronger. It breaks down.

It's not the size of the stimulus but the time between one stimulus and the next that decides the result.

   stimulus of the same size
            ↓
  ┌─────────────┬─────────────┐
  ↓             ↓             ↓
there is time  there is no    all at once,
to recover     time to        too large
               recover
  ↓             ↓             ↓
becomes        breaks down    breaks fast
stronger       gradually      and hard
(adaptation)   (chronicity)   (acute injury)

The middle is where today's story lives. The time of breaking down gradually.

The body hides it at first

This is the important part.

When a burden comes into the body, the body doesn't hurt right away. First it hides.

If one knee hurts, it shifts the load onto the other leg. If digestion is off, it eats less. If sleep is short, it drinks caffeine. If inflammation arises, it pulls out cortisol and presses it down.

All of this is compensation. It's the body's way of covering the problem and keeping daily life going.

So for a while, nothing seems to be wrong. The tests are normal too. Because they really are normal — the body is hiding it well.

Then, on the day its capacity to hide runs out, the symptom appears.

At that point the patient feels it as "sudden." But it didn't begin that day. It surfaced that day.

So the place the symptom appears is often not the cause

Someone comes in because their knee hurts, but there are cases where the knee is the side that held out for a long time. The real problem was the opposite ankle they'd stopped using years ago.

Someone comes in with palpitations, but there are cases where the heart was merely being pressed on. The real problem was a swollen belly.

When compensation goes on for a long time, the side that was compensating screams first. And we treat the place where the scream is heard.

Treat there, and it eases for a moment. But if the original problem remains, it comes back. "It gets better with treatment but keeps recurring" — that complaint usually comes from here.

Time changes the tissue itself

There is one more thing time does. It changes the very nature of the tissue.

Tissue that has been pressed for a long time, swollen for a long time, unmoved for a long time, stiffens while holding water. Its density rises and it grows heavy. Inside it, substances can't come and go, and signals don't transmit well.

What matters is that this change also takes time to reverse. Just as it didn't stiffen in a few days, it doesn't loosen in a few days.

Nerves are the same. When a pain signal repeats for a long time, the circuit that transmits that signal shifts into an amplified state. Later, even a small stimulus hurts greatly. Even after the cause is gone, the circuit remains.

To say an illness is long-standing means the illness has taken up residence in the body.

So recovery, too, has an order and a time

This is why I lay out a timetable at the first consultation.

What we're trying to reverse Roughly
Softening an over-excited reaction Days
Reviving absorption and metabolism Weeks
Changing the nature of stiffened tissue Months
Reversing an amplified nerve circuit Months, or more

All four of these exist together in one person. So some symptoms ease early, and some ease late.

If you see the ones that eased early, decide "I'm all better," and stop, then what was still in progress remains. And it builds up again.

A body that hurt for a long time recovers over a long time. This is not because the medicine is weak, but because we're reversing with time what time has done.

Why it goes back and forth between better and worse

Recovery is not a straight line. It comes like waves.

When the body recovers a little, another spot it had been hiding comes to light. The knee eases, and now the lower back hurts. It didn't get worse — its turn came.

At this point the patient feels discouraged. I try to say this part in advance — that during recovery a new place may hurt.

That said, this must be clearly distinguished from an adverse reaction caused by the medicine. If you swell, if your blood pressure rises, if you have palpitations, if your pulse is irregular, or if you feel unusually drained — that is not a wave of recovery. You should stop the medicine and let me know.

I don't use the phrase "it's part of getting better, so bear with it."

So come early

What I really want to say in this article is this.

While the body is still hiding it is the easiest time to reverse.

The period when tests turn up nothing, the period when it's a little uncomfortable but bearable. At that time only the environment has changed — the parts are still intact. It can be reversed.

By the time the symptom is distinct, the body has already lost its capacity to hide. It can still be reversed, but it takes much longer.

To those who say, "It's awkward to go to the doctor over just this much," I say that this "just this much" is a good time to come.

To speak honestly

That the nerve circuit shifts into an amplified state in chronic pain (central sensitization), that the nature of long-pressed tissue changes, that repeated stress depletes regulatory hormones — these are well-known facts.

But the viewpoint of "seeing time as one of the axes" is my interpretation. It is not a textbook classification. I use it because I think it best explains what I've seen in practice.

And not every long-standing illness reverses. Distinguishing between what can be reversed and what cannot, and telling you so — that is the line I try to hold.


The body is honest. It just doesn't say so right away.

What a body that endured for a long time needs is a treatment that waits for a long time.

A graduate of the College of Korean Medicine at Kyung Hee University, with master's and doctoral degrees in pathology — the mechanisms of disease — from its graduate school. Later served as a research professor in the university's Herbology department, studying medicinal substances. Studying both disease and medicine from both sides is the foundation of this practice: explaining "why a given medicine works for a given illness" in the language of both pathology and pharmacology. Explains autonomic, chronic, and intractable conditions — and structural problems of the body — in the language of modern science, and proposes treatment matched to the cause. Has taught prescribing and clinical practice to Korean medicine doctors for over ten years, and is a co-author of "Korean Medicine, Explained by Korean Medicine Doctors," selected for the 2018 Sejong Books list (general category).
