How Bras Can Cause Costochondritis Chest Pain

A Common Symptom of Fibromyalgia — and How to Manage It

Chest pain is one of the most alarming symptoms a person can experience. For people living with fibromyalgia, however, chest pain is often misunderstood, misdiagnosed, and frightening—especially when it stems from costochondritis, a painful inflammation of the cartilage connecting the ribs to the breastbone. Surprisingly, something as ordinary as a bra can play a significant role in triggering or worsening this condition.

What Is Costochondritis?

Costochondritis is inflammation of the costochondral joints, where the ribs attach to the sternum (breastbone). This inflammation causes localized chest pain that may feel sharp, stabbing, burning, or pressure-like. The pain often worsens with movement, deep breathing, coughing, or physical pressure.

While costochondritis can affect anyone, it is far more common in people with fibromyalgia due to heightened pain sensitivity and chronic inflammation.

Why Fibromyalgia Increases the Risk

Fibromyalgia is a disorder of pain processing. The nervous system amplifies pain signals, making sensations that might feel mildly uncomfortable to others feel intense or debilitating.

People with fibromyalgia often experience:

• Increased sensitivity to pressure
• Muscle tension and spasms
• Chronic inflammation
• Delayed healing from repetitive stress

These factors make the chest wall and rib joints particularly vulnerable.

How Bras Can Trigger or Worsen Costochondritis

1. Excessive Pressure on the Rib Cage

Underwire bras, tight bands, and structured cups place constant pressure on the ribcage. Over time, this pressure can irritate the cartilage between the ribs and sternum, triggering inflammation.

2. Restricted Chest Movement

Bras that are too tight restrict natural chest expansion during breathing. This constant restriction can strain the chest wall muscles and joints, especially in people who already have muscle stiffness from fibromyalgia.

3. Poor Fit or Incorrect Sizing

Many people wear bras that are too small, too tight, or improperly fitted. A bra that digs into the sternum, sides, or underarms can aggravate sensitive trigger points and costochondral joints.

4. Prolonged Wear

Wearing a bra for long hours without breaks—especially during flares—prevents irritated tissue from recovering and increases inflammation.

5. Heightened Nerve Sensitivity

In fibromyalgia, even light pressure can feel painful. What feels like “support” to one person may feel like intense chest pain to someone with fibromyalgia.

What Costochondritis Pain Feels Like

Many people mistake costochondritis pain for heart-related problems. Common symptoms include:

• Sharp or aching pain in the center or left side of the chest
• Pain that worsens when pressing on the chest
• Increased pain with movement or deep breathing
• Pain radiating to the shoulders, arms, or back
• Tenderness along the breastbone or ribs

Important: Always seek medical evaluation for new or severe chest pain to rule out cardiac causes.

How to Reduce Bra-Related Chest Pain

1. Switch to Wireless Bras

Choose bras without underwire. Soft, wireless bras or bralettes reduce pressure on the ribs and sternum.

2. Prioritize Proper Fit

Get professionally measured or use a trusted fitting guide. Look for bras with:

• Wide bands
• Soft, stretchy fabric
• Adjustable straps
• No digging or pinching

3. Limit Wear Time

Remove bras whenever possible, especially at home. Giving your chest wall regular breaks can significantly reduce inflammation.

4. Choose Fibromyalgia-Friendly Options

Many people find relief with:

• Seamless bras
• Front-closure bras
• Light-support sports bras
• Camisoles with built-in support

5. Apply Heat or Cold

Heat can relax tight muscles, while cold can reduce inflammation. Use whichever feels best during a flare.

6. Gentle Stretching

Light chest and shoulder stretches can help reduce stiffness and improve mobility without aggravating pain.

7. Address Underlying Fibromyalgia Flares

Managing overall fibromyalgia symptoms—sleep, stress, pacing, and inflammation—often reduces the frequency and severity of costochondritis pain.

When to See a Doctor

Seek medical attention if:

• Chest pain is new, severe, or sudden
• Pain is accompanied by shortness of breath, dizziness, or nausea
• Symptoms do not improve with rest or bra changes
• Pain interferes with daily functioning

A healthcare provider can confirm costochondritis, rule out other conditions, and recommend appropriate treatment.

Final Thoughts

For people with fibromyalgia, everyday items like bras can have a profound impact on pain levels. Costochondritis chest pain is real, common, and often overlooked—but it doesn’t have to be endured silently. By understanding the connection between bra pressure, fibromyalgia, and chest wall inflammation, many people can reduce pain, prevent flares, and regain a sense of comfort and control.

Listening to your body—and choosing comfort over convention—is not weakness. It’s self-care.
