Costochondritis: Symptoms, Diagnosis and Treatment

Overview

Costochondritis is inflammation of the cartilage connecting the ribs to the sternum (breastbone). It's a common cause of chest wall pain, and while generally not serious, it can be alarming because the pain can closely mimic heart-related chest pain, causing significant anxiety and often emergency room visits to rule out cardiac causes.

The exact cause is often unclear, though it can follow physical strain, repetitive activity, viral infections, or minor chest trauma. It's more common in adolescents and young adults, but can occur at any age. It's generally a self-limiting, benign condition, though it can be prolonged and recurrent in some people, particularly those with other chronic pain conditions like fibromyalgia.

While costochondritis itself isn't dangerous, appropriately ruling out more serious causes of chest pain (cardiac, pulmonary) is an important first step whenever new chest pain occurs — this diagnosis should never be assumed without that evaluation, especially for first-time or changing chest pain.

Symptoms

Sharp or aching pain at the front of the chest, typically where ribs meet the breastbone
Pain that worsens with deep breathing, coughing, physical activity, or specific movements

Diagnosis

Ruling out cardiac and other serious causes first — especially for new or first-time chest pain, this typically involves an EKG, and sometimes additional cardiac workup, particularly in older patients or those with cardiac risk factors
Physical exam — reproducing the pain by pressing on the costochondral joints (where rib meets breastbone) is a key diagnostic sign; if pressing reproduces the exact pain, this strongly supports costochondritis
Imaging — generally not needed for typical cases, but a chest X-ray may be done to rule out other causes if the picture is unclear
Diagnosis of exclusion — once cardiac, pulmonary, and other serious causes are reasonably excluded, and the exam is consistent, costochondritis can be diagnosed clinically

A primary care physician typically diagnoses and manages this, often after emergency or urgent evaluation has ruled out cardiac causes for new chest pain.

Treatments

Reassurance and education — understanding that this is a benign, self-limiting musculoskeletal condition significantly reduces anxiety, which itself can worsen the pain experience
NSAIDs — ibuprofen or naproxen, first-line for pain relief
Heat or ice — applied to the affected area for symptomatic relief
Activity modification — temporarily avoiding activities that clearly worsen pain (heavy lifting, certain exercises)
Physical therapy — for prolonged or recurrent cases, gentle stretching and posture work can help
Topical treatments — topical NSAIDs or lidocaine patches for localized relief
Time — most cases resolve within a few weeks to months, though some people have recurrent episodes

Your Care Plan

A step-by-step guide to navigating your condition, from finding the right doctors to advocating for the care you deserve.

Step 1: Doctors to See

Start with: Emergency or urgent care for any new, severe, or concerning chest pain, especially with risk factors for heart disease — this needs to be ruled out first, every time.

Then, once serious causes are excluded, follow up with: Your primary care physician for ongoing management.

Consider adding:

Physical therapist — for recurrent or prolonged cases
Rheumatologist — rarely needed, but considered if costochondritis is frequently recurrent alongside other chronic pain symptoms (possible fibromyalgia overlap)

Step 2: Advocate for Yourself

Never assume chest pain is costochondritis without appropriate medical evaluation first, especially for new or changing pain — always seek prompt evaluation to rule out cardiac or other serious causes. Once costochondritis is diagnosed and serious causes excluded, don't let ongoing anxiety about the pain drive repeated emergency visits — ask your primary doctor for a clear, individualized plan for what specific new or different symptoms would warrant re-evaluation versus what's expected as part of costochondritis itself, which can help reduce anxiety and unnecessary repeat testing.

Step 3: Your Action Plan

Seek prompt medical evaluation for any new chest pain to rule out cardiac or other serious causes.
Once other causes are excluded and the exam is consistent, get a costochondritis diagnosis from your primary doctor.
Start NSAIDs and heat/ice for symptom relief.
Modify activities that clearly worsen your pain temporarily.
If pain persists beyond a few weeks, consider physical therapy for stretching and posture work.
Ask your doctor for clear guidance on what new symptoms would warrant re-evaluation, to help manage anxiety about recurring pain.
