The Pain-Spasm-Ischemia Cycle: Why Pain Keeps Getting Worse (Even Without a New Injury)

Massage therapists, if you’ve ever had a client say, “It just keeps getting worse,” and nothing new has happened, you’re not imagining things, and neither are they. During my clinical work at the European Massage Therapy School and also as a Las Vegas massage therapist with my own massage practice, I have seen this occur in my clientele.

What you’re often seeing is a well-documented physiological loop called the pain–spasm–ischemia cycle (also known as the pain-tension cycle). Once you understand this sequence, a lot of chronic pain patterns start to make sense.

Let’s walk through it the way it actually shows up in the body.

The Pain-Tension Cycle, aka The Pain-Spasm-Ischemia Pain Cycle

It Starts with Pain

The cycle begins with some kind of input that triggers the brain to broadcast a pain signal. That might be an injury, repetitive strain, or even long-term postural tension. At first, the pain is usually specific and localized. The body is doing exactly what it’s supposed to do, it's sending a signal that something needs attention.

The Body Tries to Protect You

In response to that pain signal, the nervous system contracts the surrounding muscles to stabilize and protect the area. This is a normal, natural response that our nervous system is designed for. It’s your body creating a brace. The issue isn't the contraction, it’s when that contraction stays contracted longer than it needs to. What started as protection becomes restriction.

Circulation Gets Compromised

When muscles stay contracted, they begin to compress the local blood vessels. Less space means less blood flow. Now the tissue isn’t just tight, it’s also under-supplied with the necessary blood flow. Circulation drops, and with it, the delivery of oxygen and nutrients that the tissue needs to function.

Ischemia: Oxygen Drops, Stress Goes Up

As circulation decreases, oxygen delivery to the tissue also decreases. This creates a state known as ischemia (iss-SKEEM-ee-a), where the tissue isn’t receiving adequate oxygen. At this point, the body is still trying to adapt. But now it’s doing so with limited resources.

Waste Builds Up

The body increases metabolic activity in an attempt to compensate. But without proper circulation, waste products don’t clear efficiently. So instead of resolving the issue, the environment inside the tissue becomes more chemically irritating. You start to see a buildup of metabolic byproducts like lactic acid, along with other waste materials that would normally be flushed out through healthy circulation.

The Pain Changes to Ischemic Pain and Intensifies

This buildup leads to ischemic pain, which tends to feel different from the original pain. Clients might describe their pain as:

• More diffuse

• Harder to pinpoint

• Deeper

• More persistent

And here’s the key: the nervous system reads this as a new threat. So what does it do? It contracts again.

The Cycle Repeats

More contraction leads to more compression. More compression leads to less circulation. Less circulation leads to more ischemia. More ischemia leads to more pain. And just like that, the body is stuck in a loop where pain is generating more pain. This is why chronic pain can escalate over time—even when there hasn’t been a new injury. The system is feeding itself.

What This Means for Massage Therapy

Once you understand the pain–spasm–ischemia cycle, as a massage therapist, your approach to treatment shifts. You’re no longer trying to “force” tissue to release or chase symptoms from one spot to another. You’re working with a complex system that needs to be calmed (nervous system), supported (soft tissue and musculatory system), and re-supplied (circulatory system).

Effective treatment focuses on:

• Restoring circulation

• Reducing unnecessary muscle contraction

• Supporting oxygen delivery to the tissue

• Calming the nervous system

This is where slower, more intentional bodywork becomes so valuable. When the tissue feels safe enough to stop guarding, circulation improves. When circulation improves, the chemistry of the tissue changes. And when that happens, the cycle can finally begin to find balance again.

The Bigger Picture

Pain isn’t always just about the original injury. Often, it’s about what happened afterward. It's about how the body adapted, compensated, and got stuck in a protective loop. I see my role as a bodyworker is to recognize that pattern and help guide the body out of it, not by overpowering it or rushing it. But by working with it in a way that restores balance. Because once the cycle is interrupted, the body does what it’s designed to do: It heals.
