Fibromyalgia vs Myofascial Pain Syndrome: What Is the Difference?

Fibromyalgia and myofascial pain syndrome are two of the most commonly confused chronic pain conditions. They share some surface similarities – both involve muscle pain, both are more common in women, and neither shows up clearly on standard imaging. But they are fundamentally different in how they develop, how they present and how they should be treated.

Getting the distinction right matters because the wrong treatment approach for either condition can make things worse.

The key difference

The most important distinction between the two conditions is where the primary problem lies.

Myofascial pain syndrome is a peripheral condition. The problem is in the muscles and fascia themselves, specifically in trigger points which are hyperirritable knots of contracted muscle fibre that generate local and referred pain. The nervous system processes pain normally. The issue is the source of the pain signal.

Fibromyalgia is a condition where the brain and spinal cord process pain signals differently. As researchers at the Mayo Clinic describe it, the brain’s pain receptors develop a kind of memory of pain and can begin to overreact to both painful and non-painful signals. The muscles and fascia may not have significant structural issues but the experience of widespread pain is very real.

How the pain differs

Myofascial pain syndrome typically presents as regional pain concentrated in specific areas related to the trigger points involved. There are identifiable tender spots that reproduce the pain when pressed and the referred pain follows predictable patterns. The pain tends to be more clearly related to movement or posture.

Fibromyalgia presents as widespread pain affecting multiple regions of the body simultaneously, often described as an all-over aching or burning. It is also more commonly associated with fatigue, sleep disturbance and cognitive symptoms such as brain fog. The sensitivity is more global rather than localised to specific trigger points.

Can you have both?

Yes. Myofascial pain syndrome and fibromyalgia can and do occur together. Active trigger points are very common in people with fibromyalgia and contribute to their overall pain experience. Treating the trigger points through myotherapy can meaningfully reduce pain even in fibromyalgia by reducing the peripheral input contributing to the widespread pain experience.

This overlap is one of the reasons the conditions are confused. The reality is often more complex than either diagnosis alone and a thorough clinical assessment is the only way to understand what is actually going on.

How treatment differs

Myofascial pain syndrome typically responds well to targeted manual therapy, dry needling and a corrective exercise program aimed at the underlying movement dysfunction. Progress tends to be more linear and more directly related to physical treatment.

Fibromyalgia requires a broader approach. Treatment is lighter and more carefully dosed. The movement component is graded more gradually. Pain education is an essential part of the process. Progress is less linear and requires more patience.

At Back to Life Pain Clinic, assessment always clarifies which condition is present before treatment begins. The two require different approaches and combining them without clarity leads to inconsistent results.
