Fibromyalgia Chest Pain: Causes, Symptoms, and When to Worry
Fibromyalgia Chest Pain: Causes, Symptoms, and When to Worry
The infographic below explains the most common symptoms and causes of fibromyalgia chest pain, including costochondritis and muscle inflammation.
Chest pain is one of the most frightening symptoms a person can experience. Many people immediately worry about heart problems when they feel pain or pressure in their chest.
However, for people living with fibromyalgia, chest pain can occur for a completely different reason. Fibromyalgia chest pain is often related to muscle inflammation, nerve sensitivity, and a condition known as costochondritis.
Although the pain can feel intense and alarming, it is usually not caused by heart disease. Understanding how fibromyalgia affects the chest muscles and nerves can help patients recognize symptoms and seek appropriate care.
In this guide, we will explore the causes of fibromyalgia chest pain, how it feels, common triggers, treatment options, and when chest pain requires urgent medical attention.
What Is Fibromyalgia?
Fibromyalgia is a chronic condition that affects how the brain and nervous system process pain signals. People with fibromyalgia experience widespread musculoskeletal pain along with fatigue, sleep disturbances, and cognitive difficulties often referred to as "fibro fog."
Research suggests that fibromyalgia amplifies pain signals in the brain, causing even mild physical stimuli to feel painful.

Can Fibromyalgia Cause Chest Pain?
Yes. Many people with fibromyalgia report episodes of chest pain that can feel sharp, burning, or pressure-like.
This pain usually originates from muscles and connective tissues around the ribs and breastbone rather than from the heart.
Because fibromyalgia increases pain sensitivity, inflammation or strain in the chest wall muscles may trigger intense discomfort.
For many patients, the sensation can feel similar to a heart attack, which is why chest pain should always be evaluated by a healthcare professional if it occurs suddenly or severely.
⚠️ WARNING: Most Fibromyalgia Patients Are Treating It WRONG
If you don’t understand what fibromyalgia really is, you might be making your symptoms worse without even realizing it.
👉 Read This Before It Gets WorseWhat Does Fibromyalgia Chest Pain Feel Like?
Fibromyalgia chest pain can vary from person to person, but many patients describe similar sensations.
- Sharp or stabbing pain in the chest
- Burning sensation near the ribs or breastbone
- Tightness or pressure in the chest muscles
- Pain that worsens when breathing deeply
- Localized tenderness when touching the chest area
The pain may come and go and is often worse during fibromyalgia flare-ups.

The Link Between Fibromyalgia and Costochondritis
One of the most common causes of chest pain in fibromyalgia patients is costochondritis.
Costochondritis is an inflammation of the cartilage that connects the ribs to the breastbone.
When this cartilage becomes inflamed, it can cause sharp pain in the chest that may worsen with movement or deep breathing.
Because fibromyalgia increases sensitivity to pain, even mild inflammation in this area may feel severe.
Why Fibromyalgia Causes Chest Pain
Several mechanisms may contribute to chest pain in people with fibromyalgia.
Central Sensitization
Fibromyalgia changes how the brain processes pain signals. This phenomenon is known as central sensitization.
As a result, the nervous system amplifies pain signals coming from muscles and connective tissues.
Muscle Tension
Chronic muscle tension around the shoulders, ribs, and chest wall can create persistent discomfort.
Nerve Sensitivity
Heightened nerve sensitivity may cause normal sensations to feel painful.
Poor Sleep
Sleep disturbances can worsen pain perception and inflammation.

Common Triggers of Fibromyalgia Chest Pain
Certain factors may increase the likelihood of chest pain episodes in fibromyalgia patients.
- Stress and anxiety
- Poor posture
- Physical overexertion
- Lack of sleep
- Cold weather
- Fibromyalgia flare-ups
How to Tell the Difference Between Fibromyalgia Chest Pain and Heart Pain
One of the biggest concerns people have when experiencing chest pain is whether it may be related to heart disease.
Although fibromyalgia chest pain usually originates from muscles and connective tissues, it is important to recognize warning signs of heart problems.
Many people with fibromyalgia worry that chest pain could be a heart attack. The infographic below explains the key differences between fibromyalgia chest pain and heart attack symptoms.
Comparison infographic showing the key differences between fibromyalgia chest pain and heart attack symptoms.
Fibromyalgia Chest Pain
- Often localized
- Tender to touch
- Worsens with movement or breathing
- Associated with other fibromyalgia symptoms
Possible Heart-Related Chest Pain
- Pressure or squeezing sensation
- Pain spreading to the arm, jaw, or back
- Shortness of breath
- Nausea or sweating
If chest pain occurs suddenly or is accompanied by severe symptoms, immediate medical attention is essential.
How Fibromyalgia Chest Pain Is Diagnosed
Because chest pain can have many causes, doctors usually perform tests to rule out heart disease and other medical conditions.
Diagnostic evaluation may include:
- Physical examination
- Electrocardiogram (ECG)
- Blood tests
- Imaging tests
Doctors may also evaluate widespread pain and other symptoms consistent with fibromyalgia.

Treatment Options for Fibromyalgia Chest Pain
Although fibromyalgia cannot currently be cured, several treatment approaches can help reduce chest pain symptoms.
Medication
Doctors may prescribe medications that help regulate pain signals in the nervous system.
Physical Therapy
Gentle stretching and strengthening exercises may help relieve muscle tension.
Stress Management
Stress can worsen fibromyalgia symptoms. Relaxation techniques such as meditation and breathing exercises may help reduce flare-ups.
Exercise
Regular low-impact exercise can improve pain tolerance and overall function.

When to See a Doctor
Chest pain should never be ignored. Even if you have fibromyalgia, it is important to seek medical evaluation when experiencing new or severe chest pain.
Seek immediate medical attention if chest pain is accompanied by:
- Shortness of breath
- Fainting
- Severe pressure in the chest
- Pain spreading to the arm or jaw
Living With Fibromyalgia Chest Pain
Although chest pain can be alarming, many people with fibromyalgia learn to manage symptoms with the right combination of treatments, lifestyle adjustments, and stress management strategies.
Understanding the triggers and patterns of fibromyalgia pain can help patients reduce flare-ups and improve quality of life.
Key Takeaways
- Fibromyalgia can cause chest pain due to muscle inflammation and nerve sensitivity.
- Costochondritis is a common cause of chest pain in fibromyalgia patients.
- The pain often originates from the chest wall rather than the heart.
- Chest pain should always be evaluated to rule out heart disease.
- Proper treatment and lifestyle strategies can help manage symptoms.
