Experiencing chest pain can naturally set off alarm bells, prompting immediate concerns about cardiac issues or other serious conditions. However, for individuals living with fibromyalgia, distinguishing between fibro-related chest pain and other causes can pose a unique challenge.
According to a study published in Arthritis Research & Therapy, 54% of people in the study with fibromyalgia reported experiencing chest pain, a significantly higher prevalence compared to 4% in the control group [1].
In this article, we unravel the complexities of fibromyalgia chest pain, offering insights to help you navigate this often perplexing aspect of fibro and providing practical tips for relief and management

At a Glance: Does Fibromyalgia Cause Chest Pain? Yes, chest pain is a recognised and common symptom of fibromyalgia, affecting over half of those diagnosed with the condition. It most often stems from muscle tension, heightened nerve sensitivity, or a related condition called costochondritis (inflammation of the cartilage connecting ribs to the breastbone). While fibromyalgia-related chest pain is rarely dangerous, any new or severe chest pain should always be assessed by a doctor to rule out cardiac causes. |
What Does Fibromyalgia Chest Pain Feel Like?
Unlike acute cardiac-related chest pain, fibromyalgia chest pain tends to be more diffuse and chronic, often lasting for extended periods.
Additionally, fibro chest pain may fluctuate in intensity and is frequently accompanied by other fibromyalgia symptoms such as fatigue and muscle stiffness.
Fibro chest pain can manifest in various ways, ranging from a dull ache or pressure to sharp, stabbing sensations. It may feel like tightness or discomfort across the chest or radiate to the shoulders, arms or back.
Importantly, it's crucial to trust your body's signals and seek medical attention if you’re worried about chest pain - especially if it's accompanied by symptoms like shortness of breath, dizziness or nausea.
What Causes Fibro Chest Pain?
Fibromyalgia is a long-term condition known for causing widespread muscle pain, fatigue, sleep problems, and mood swings. Though researchers continue to study it, the exact reasons behind fibromyalgia remain a bit of a mystery.
However, experts suspect that a combination of factors, like genetics, environment and how the body processes pain, may all play a role in its development and how long it sticks around.

Chest pain associated with fibromyalgia can result from:
1. Muscle tension and trigger points
Fibromyalgia often involves widespread muscle pain and tension throughout the body, including the chest area. Trigger points, which are sensitive areas in muscles, can cause localised pain that may radiate to the chest.
2. Costochondritis
This condition involves inflammation of the cartilage that connects the ribs to the sternum (breastbone). It can cause chest pain that may mimic the pain of a heart attack. The NHS patient guidance confirms that people with fibromyalgia develop costochondritis more frequently than the general population.[2]
3. Stress and anxiety
Fibromyalgia is often associated with heightened stress levels and anxiety, which can manifest as chest pain or discomfort due to muscle tension and increased heart rate.
4. Sensitivity of the nerves
Fibromyalgia may involve a heightened sensitivity to pain, including in the chest area. Nerves become more sensitive, leading to increased perception of pain.
5. Other underlying conditions
Fibro often coexists with other conditions, such as irritable bowel syndrome (IBS), acid reflux or temporomandibular joint (TMJ) disorder, which can also contribute to chest pain.

Other Causes Of Chest Pain That Aren’t Fibromyalgia
When it comes to chest pain, it's essential to consider that not all discomfort is linked to fibromyalgia. Here are some other common causes of chest pain worth evaluating to help pinpoint the underlying cause of pain.
1. Musculoskeletal issues
Strained muscles, rib cage injuries, or inflammation of the chest wall can all lead to chest discomfort.
2. Gastrointestinal problems
Acid reflux, gastritis or oesophageal spasms can cause chest pain that may be mistaken for heart-related issues.
3. Respiratory conditions
Pneumonia, bronchitis, or asthma exacerbations can trigger chest tightness or pain.
4. Anxiety and panic attacks
Intense stress or anxiety can manifest as chest pain, often accompanied by rapid heartbeat and shortness of breath.
5. Heart-related issues
While less common, conditions like angina, heartburn, or pericarditis can present with chest pain requiring prompt medical attention.
6. Other medical conditions
Conditions such as shingles, costochondritis or gallbladder disease may also cause chest discomfort.
Remember, if you experience sudden, severe chest pain, shortness of breath, dizziness or any other concerning symptoms, it's crucial to seek urgent medical attention to rule out serious conditions like a heart attack or pulmonary embolism.
Should I Push Through Fibromyalgia Pain?
Pushing through fibromyalgia pain, whether it's in the chest or elsewhere, isn't always the best approach. While it's natural to want to soldier on, listening to your body and pacing yourself can be more beneficial in the long run. When it comes to chest pain, it's essential to be more alert and less likely to push through it, as it can sometimes indicate more serious underlying issues that require prompt medical attention.
It's important to remember that fibromyalgia itself won't cause physical damage or get worse over time [3], even if it feels that way during flare-ups. Instead of pushing through the pain, focus on finding strategies to manage it effectively.
Pain management programmes (PMPs) often include tools and techniques for coping with flare-ups, such as pacing activities, practising relaxation techniques and learning to prioritise self-care. By incorporating these strategies into your daily routine, you can better manage fibromyalgia symptoms and improve your overall quality of life [4].

FAQ’s- About Fibro And Chest Pain
Can fibromyalgia chest pain last for days or weeks?
Yes. Unlike acute chest pain, fibromyalgia-related chest discomfort can persist for days or weeks, often fluctuating alongside other fibro flare-up symptoms.
How does medical cannabis work for fibromyalgia chest pain?
The THC and CBD interact with the body's endocannabinoid system. It reduces pain signal intensity and calms the nerve hypersensitivity that drives amplified chest pain in fibromyalgia.
What medications must I try before medical cannabis at Leva?
You should have tried at least two conventional treatments, such as pregabalin, duloxetine, or amitriptyline, before a cannabis-based prescription is considered.
Is It possible that my hormonal changes make fibromyalgia chest pain worse?
Hormonal fluctuations during menstruation, perimenopause, or menopause may contribute to increased pain sensitivity and worsening fibromyalgia symptoms in some individuals.
Can fibromyalgia chest pain radiate to other parts of the body?
Yes. Trigger points and costochondritis in the chest commonly radiate pain to the upper back, shoulders, and arms, making it easy to misdiagnose.
