Chest Pain And Rheumatoid Arthritis: Causes & Treatment

Rheumatoid arthritis (RA) primarily affects joints, but its inflammatory effects can extend to the chest, causing pain that alarms patients. This expert Q&A addresses common concerns about chest pain in RA, drawing from rheumatology insights to clarify causes, symptoms, differentiation from heart problems, treatments, and prevention strategies.

Question: Sometimes it feels like the bones in my chest hurt. Is it RA or am I having heart problems?

Pain in the chest bones among RA patients is most often due to

costochondritis

, inflammation of the cartilage connecting the ribs to the breastbone (sternum). This occurs where ribs meet the sternum at seven points, frequently on the left side, mimicking heart-related pain but remaining localized. Unlike a heart attack, costochondritis pain worsens with deep breathing, coughing, or pressing on the ribs and does not radiate with nausea or lightheadedness.

RA’s systemic inflammation targets costochondral joints, similar to hand or knee joints, though less commonly. Sharp, aching, or pressure-like pain affects one or more ribs, often the upper left ones. Costochondritis accounts for about one-third of chest pain visits to providers and is benign, causing no permanent damage.

How Does Costochondritis Relate to Rheumatoid Arthritis?

In RA, chronic inflammation inflames costosternal and costochondral junctions, leading to tenderness reproducible by palpation—a hallmark absent in cardiac pain. This differs from pleurisy (lung lining inflammation), which causes sharp pain on breathing but lacks focal tenderness. Other arthritic conditions like psoriatic arthritis (PsA) or axial spondylarthritis also provoke chest wall inflammation.

• Key Triggers in RA: Autoimmune attack on cartilage, exacerbated by flares.
• Prevalence: Not rare in RA, though hands/elbows/knees are more typical sites.
• Associated Factors: Coughing strains, chest injuries, infections, or repetitive exertion.

Fibromyalgia, common in RA patients, adds widespread tenderness, including central chest stabbing around the breastbone. Septic arthritis or SAPHO syndrome (synovitis, acne, pustulosis, hyperostosis, osteitis) are rarer but feature anterior chest wall involvement with skin lesions or osteomyelitis.

Symptoms of Costochondritis in RA Patients

Chest pain from costochondritis feels sharp, aching, or like pressure, radiating to arms/shoulders but staying chest-localized. It intensifies with chest wall movement, deep breaths, coughing, sneezing, or twisting.

Symptom	Description	RA-Specific Note
Pain Quality	Sharp/aching/pressure; worsens on palpation	Localized to 2nd-5th ribs near sternum
Triggers	Breathing, coughing, arm/shoulder use	Overlaps with RA flares
Duration	Days to weeks; self-resolves often	Chronic in inflammatory arthritis
Other Signs	Tenderness without swelling; no fever/SOB	Distinguishes from infection/pleurisy

In PsA, similar cartilage inflammation causes dull aches or severe sharpness mistaken for heart attacks. Intercostal muscle strains from torso twists add stabbing pain evolving to dull aches with spasms.

Ruling Out Serious Causes: Heart Disease Risk in RA

RA doubles cardiovascular disease (CVD) risk due to chronic inflammation accelerating atherosclerosis, endothelial damage, high uric acid, and comorbidities like hypertension. PsA patients share this elevated CVD profile.

Red Flags for Cardiac Involvement:

• Chest pressure/tightness radiating to jaw/neck/arm/abdomen
• Shortness of breath, nausea, sweating, dizziness
• Cold/numb limbs, unrelated to movement

Always seek emergency care for chest pain to exclude myocardial infarction or pneumonia—costochondritis is a diagnosis of exclusion. RA inflammation promotes plaque buildup, narrowing arteries.

Treatment Options for Chest Pain in RA

Costochondritis management focuses on symptom relief and underlying RA control. No damage occurs, so treatments are conservative.

1. RA Disease Modification: DMARDs (methotrexate), biologics (TNF inhibitors) reduce systemic inflammation, preventing flares.
2. Pain Relief: NSAIDs (ibuprofen) for short-term use; acetaminophen for milder pain. Avoid long-term NSAIDs due to GI/CV risks in RA.
3. Local Therapies: Ice/heat packs, topical NSAIDs, or lidocaine patches on tender spots.
4. Physical Measures: Rest, posture correction, gentle stretching; avoid aggravating activities.
5. Injections: Corticosteroid shots into costochondral junctions for refractory cases.

PsA treatments mirror RA, emphasizing inflammation control to lower CVD risk. Fibromyalgia needs multidisciplinary care: exercise, CBT, low-dose antidepressants.

Prevention and Long-Term Management

Lifestyle modifications mitigate RA chest complications:

• Maintain RA remission with medications and regular rheumatologist visits.
• Monitor CVD risks: Control cholesterol, blood pressure, quit smoking, exercise 150 min/week.
• Strengthen chest muscles gradually to prevent strains.
• Report new/worsening chest pain promptly.

Early RA diagnosis and tight control slash extra-articular manifestations like costochondritis by 50% per studies.

Frequently Asked Questions (FAQs)

Q: Can RA cause chest pain without joint involvement?

A: Yes, via costochondritis or pleurisy; inflammation targets chest cartilage independently.

Q: How do I differentiate costochondritis from a heart attack?

A: Costochondritis pain is reproducible by pressing ribs, worsens with breath/movement, lacks radiation/nausea. Seek ER if unsure.

Q: Is chest pain in RA always costochondritis?

A: No; also CVD, muscle strain, fibromyalgia, or rare infections. Full evaluation needed.

Q: What if over-the-counter painkillers don’t help?

A: See your doctor for RA optimization, injections, or CVD screening.

Q: Does PsA cause similar chest issues?

A: Yes, costochondritis and heightened CVD risk from shared inflammation.

Key Takeaways
