How Long It Takes for Pain to Become Chronic

"This is chronic now, so it's difficult."

This is what people who have hurt for a long time hear elsewhere and bring to me. I accept this statement only halfway. It is true that things become difficult once pain is chronic. But once you understand why it becomes difficult, you can also see where to work.

Why it keeps hurting when nothing is injured

Pain is originally a warning. It is a signal saying: there is an injured place, so be careful. So when the injured place heals, the signal should stop too.

But when pain continues for a long time, a strange thing happens in the body. The nerve circuit that carries the pain signal itself changes.

The point where nerve meets nerve is called a synapse. When the pain signal keeps passing through, this connection grows stronger and stronger — just as a frequently traveled road widens. Then what happens?

• Even a small stimulus hurts greatly
• Stimuli that shouldn't hurt (a brush, a collar) start to hurt
• Even after the injured place has fully healed, only the pain remains
• The painful area grows wider than it was at first

Pain begins to roll on by itself, apart from its cause.

The three-month and six-month timeline

This change does not happen overnight. The rough flow looks like this.

Period	What happens in the body
~3 months	Changes in the nerve connections begin. Still an easy time to reverse
3–6 months	The changes settle in. Pain begins to separate from its cause
6 months~	The circuit hardens. Reversing it needs both time and method

This is where the mention of three months and six months comes from. It is not an exact clock. It differs from person to person, and by the type of pain. But the direction — the longer it's left, the more it hardens — is clear.

That is why I do not say to those who have hurt for a long time, "Why did you only come now?" Instead, I calculate together with them "how long it will take from here."

And yet a hardened circuit can be undone

This is the important part.

The property by which a nerve circuit grows stronger means, conversely, that it can also grow weaker. The very property that hardened the circuit is also used to undo it. A nerve is not a hardened stone but a tissue that keeps relearning.

The recovery period spoken of in this field recently is roughly around two months. If it took a few months to harden, I had thought it would take a similar time to undo. But in fact, observations are accumulating that recovery may be faster.

There is one condition, though. It does not undo by being left alone.

What undoes the circuit

Undoing a hardened pain circuit needs two directions together.

First, the signal that keeps rising must be reduced. As long as the signal keeps rising from the painful place, the circuit keeps packing down that road. Tissue hardened by high pressure, pooled fluid, inflammation that won't cool — these are the sources of the signal. We must work on these.

Second, the circuit itself must be given new experience. It needs the experience of moving without pain, of being stimulated safely. That is why I always add movement alongside, in proportion to how much the pain has decreased. There is almost no chronic pain that heals by rest alone.

Here is where the roles of herbal medicine, acupuncture, and manual therapy diverge.

• Manual therapy and acupuncture — release the hardened tissue and reduce the signal rising now
• Herbal medicine — delivers to the body a continuous signal that lasts all day long. This is the part that works even in the hours after you leave the treatment room
• Movement — engraves new experience onto the circuit

Intermittent treatment alone is not enough, and medicine alone is not enough. The three must look in the same direction.

And so recovery comes like a wave

The process of an old pain healing is not a straight line. It repeats improving and worsening. Many people despair at this point. "So it can't be done after all," they think.

I see it this way. Recovery is the gradual shrinking of the wave's amplitude. Even on days that get worse, if the bottom is growing slightly shallower, the direction is right.

So I look not only at how good the good days were, but together with you at how much less bad the bad days became.

Finally

For chronic pain I will not promise an exact period. The speed of nerve recovery differs from person to person, and even the periods I've described here are an area still being freshly uncovered.

But the one sentence I do not accept is "it's chronic, so nothing can be done." That it has hardened does not mean it cannot be reversed — it means reversing it requires order and time.

However many years you have been hurting now, that circuit was relearning yesterday and is relearning today. What we let it learn can still be decided.
