Pain isn’t always felt where the problem actually begins. You may have pain in your arm that’s coming from your neck, discomfort in your leg that’s originating in your lower back, or aching in your shoulder that’s caused by a tight muscle elsewhere. This is one reason diagnosing pain can be challenging.

Two conditions that are commonly confused are myofascial trigger points and radicular pain. Both can cause pain that travels away from its source, but they develop for very different reasons and require different treatment approaches. Understanding the difference can help you receive the right treatment and recover more effectively.

What Are Myofascial Trigger Points?

Tight Bands Within a Muscle

A myofascial trigger point is a small, highly sensitive area within a tight band of muscle. These spots develop when muscle fibers remain contracted instead of fully relaxing.

Trigger points may form after an injury, repetitive movements, prolonged poor posture, stress, or muscle overuse. Once they develop, they can become painful both during movement and at rest.

Trigger Points Can Cause Pain Elsewhere

One of the unique characteristics of trigger points is referred pain.

Instead of hurting only where the muscle is tight, a trigger point can create pain in a completely different area. For example, a trigger point in the upper trapezius may produce pain along the side of the neck or into the head, while a trigger point in the gluteal muscles may create discomfort that extends down the leg.

This often leads people to believe the painful area is the source of the problem when it actually isn’t.

What Is Radicular Pain?

Pain Caused by an Irritated Nerve

Radicular pain occurs when a spinal nerve becomes compressed or irritated, usually as it exits the spine.

Common causes include herniated discs, arthritis, spinal stenosis, or inflammation around the nerve root. Because nerves travel throughout the body, irritation at the spine can produce symptoms far away from the original source.

This is why a problem in the neck may cause symptoms in the hand or why a problem in the lower back may produce pain extending into the foot.

The Nervous System Is Involved

Unlike trigger points, radicular pain involves the nervous system.

The irritated nerve disrupts normal communication between the brain and the affected area, often producing symptoms beyond pain alone. This difference is one of the most important ways healthcare providers distinguish radicular pain from muscle-related pain.

How Referred Pain Differs From Radicular Pain

Referred Pain Stays Within the Muscle Pattern

Pain from trigger points usually follows predictable muscle referral patterns.

Although the discomfort may spread away from the trigger point, it generally feels like an aching, dull, or deep soreness rather than sharp or electric pain. The symptoms often remain within a broad region instead of following a specific nerve pathway.

Pressing directly on the trigger point frequently reproduces both the local pain and the referred symptoms.

Radicular Pain Follows the Path of a Nerve

Radicular pain typically travels along the course of a specific nerve.

People often describe it as sharp, burning, shooting, or electric. The pain may extend from the neck into the shoulder, arm, and fingers, or from the lower back into the buttock, leg, and foot.

The symptoms often follow a narrow, predictable pattern based on which nerve is affected.

Other Symptoms Help Tell the Difference

Trigger Points Usually Don’t Cause Numbness

Trigger points may produce tenderness, aching, stiffness, and reduced flexibility.

However, they rarely cause numbness, tingling, or significant muscle weakness because the nerve itself is not being compressed.

The affected muscle may feel tight or fatigued, but sensation usually remains normal.

Radicular Pain Often Includes Neurological Symptoms

Because radicular pain involves a nerve, symptoms often include tingling, numbness, reduced sensation, or weakness in addition to pain.

Some people notice difficulty gripping objects, lifting the foot while walking, or performing everyday activities because the affected muscles are not receiving normal nerve signals.

These neurological symptoms deserve prompt evaluation.

Why Getting the Diagnosis Right Matters

The Treatments Are Different

Although both conditions can produce pain away from the source, the treatment approach is very different.

Trigger points often respond well to manual therapy, stretching, strengthening, movement retraining, and correcting the factors that caused the muscle to become overloaded.

Radicular pain focuses on reducing pressure on the affected nerve while improving spinal mobility, strength, posture, and movement patterns that contribute to nerve irritation.

Treating a nerve problem like a muscle problem, or vice versa, often delays recovery.

Sometimes Both Conditions Are Present

In some cases, trigger points and nerve irritation occur together.

For example, someone with a pinched nerve in the neck may also develop tight muscles around the shoulders as the body tries to protect the painful area. Similarly, chronic muscle tension may increase stress on nearby joints and nerves.

A thorough evaluation helps identify all contributing factors instead of treating only one source of pain.

How Physical Therapy Identifies the Cause

A Comprehensive Assessment

Physical therapists evaluate much more than the location of your pain.

Your examination may include posture, movement patterns, muscle strength, flexibility, joint mobility, neurological testing, and special orthopedic tests designed to distinguish muscle-related pain from nerve involvement.

The goal is to determine why you’re experiencing pain instead of simply treating where it hurts.

Individualized Treatment

Every patient’s symptoms are different.

Your treatment plan may include manual therapy, trigger point techniques, stretching, strengthening exercises, nerve mobility exercises, posture correction, and movement retraining based on your specific diagnosis.

Addressing the underlying cause gives you the best opportunity for lasting improvement.

When You Should Seek Professional Help

Don’t Ignore Pain That Travels

Pain that spreads into your arm or leg should never be ignored, especially if it is becoming more frequent or more intense.

Likewise, muscle pain that repeatedly returns despite stretching or massage deserves evaluation to determine whether trigger points or another underlying problem are responsible.

Early treatment often leads to faster recovery and helps prevent chronic pain from developing.

What to Expect From Physical Therapy

Your physical therapist will determine whether your symptoms are caused by myofascial trigger points, nerve irritation, or a combination of both.

Treatment is designed to relieve pain, restore normal movement, improve strength, and reduce the likelihood that your symptoms will continue returning.

Don’t Treat the Wrong Problem

Referred pain and radicular pain may feel similar, but they have very different causes. Myofascial trigger points originate within muscles, while radicular pain results from irritation of a spinal nerve. Understanding the difference is essential because effective treatment depends on identifying the true source of your symptoms.

The physical therapy specialists at DeRosa Physical Therapy in perform comprehensive evaluations to determine exactly what’s causing your pain. Whether your symptoms are coming from trigger points, nerve irritation, or a combination of both, we’ll develop a personalized treatment plan that addresses the underlying cause and helps you return to the activities you enjoy.
