Unexplained rib & chest wall pain

Chest wall pain that nobody has explained — yet.

Months — sometimes years — of rib or chest pain. The heart checked and cleared. Scans reported as normal. Then nothing but painkillers and reassurance. Chest wall pain almost always has a findable cause: it needs a structured assessment by someone who examines the chest wall for a living.

What we actually find

The usual suspects behind “unexplained” chest wall pain

When the heart, lungs and gut have been cleared, these are the diagnoses that account for most persistent rib and chest wall pain — and most of them are made by examination.

Cartilage

Costochondritis & Tietze syndrome

Inflammation where ribs meet the breastbone: tender at specific points, worse with deep breaths and movement. Usually settles — but persistent “costochondritis” deserves a second look, because it is a common mislabel for other conditions on this list.

Nerve

Intercostal neuralgia

Burning, shooting or band-like pain along the line of a rib, from an irritated intercostal nerve — after injury, surgery, shingles, or entrapment. Responds well to targeted nerve blocks and, where needed, cryoablation.

Mechanical

Slipping rib syndrome

Sharp lower-rib pain with clicking, triggered by movement, invisible on scans. Diagnosed in minutes with the hooking manoeuvre.

Dedicated slipping rib page →
Xiphisternum

Xiphoid syndrome

Pain and tenderness at the small cartilage tip at the bottom of the breastbone, aggravated by bending, large meals or pressure. Treated with local measures, injection — and xiphoidectomy in persistent confirmed cases.

Overuse

Rib stress fractures

Seen in rowers, golfers, throwers — and after prolonged violent coughing. Often invisible on first X-rays; picked up on targeted imaging and settled with structured load management.

Post-injury

Chronic post-fracture pain

Pain persisting long after a rib fracture “healed” — usually malunion, nonunion or nerve damage. All treatable.

How the answer is found

A structured assessment — not another round of guesswork

Your story, properly taken

When it started, what triggers it, what every previous test showed. Mr Scarci reviews all existing imaging and letters before you arrive.

A real chest wall examination

Point-by-point palpation of the costal cartilages, sternum, xiphoid and rib margins — including the hooking manoeuvre most patients have never had.

Targeted tests only where they change the answer

Dynamic ultrasound, specific CT or MRI views, or bone imaging — requested to answer a question, not to fish.

A diagnostic nerve block where needed

Local anaesthetic at the suspected source that abolishes the pain confirms the diagnosis and brings relief in the same appointment.

Then treatment that fits the diagnosis

Medication done properly

Anti-inflammatories, neuropathic agents and lidocaine patches — chosen for the actual diagnosis rather than dispensed for “chest pain”.

Targeted physiotherapy

Breathing mechanics, thoracic mobility and postural drivers addressed by physiotherapists used to chest wall problems.

Nerve blocks & cryoablation

Image-guided injections for relief lasting weeks to months; cryoablation for nerves sensitised by years of irritation.

Surgery where it is the answer

Xiphoidectomy for confirmed xiphoid syndrome, refixation of painful nonunions, costal cartilage resection for slipping ribs — reserved for confirmed diagnoses that have failed conservative care.

Old injury, ongoing pain

“It healed years ago — so why does it still hurt?”

Because “healed on X-ray” and “back to normal” are not the same thing. Three specific problems explain most chronic post-fracture pain:

  • Malunion

    The rib knitted in a poor position, changing chest wall mechanics with every breath.

  • Nonunion

    The fracture never fully joined, leaving a subtly mobile, painful segment.

  • Intercostal nerve damage

    The nerve under the rib was injured or trapped in scar as things healed.

Each has a different treatment — from nerve blocks and cryoablation to surgical refixation with titanium plates — which is exactly why “learn to live with it” is rarely the right final answer.

New, unassessed chest pain? Have cardiac causes excluded first — via 999 for acute severe symptoms, or urgently through your GP or A&E. This clinic is the right next step once the heart has been cleared and the pain remains.

Patient outcomes

Patients who arrived with normal tests and no answers

★★★★★

“Two A&E visits, a normal angiogram, and six months of pain. I was starting to believe it was in my head. Mr Scarci found the exact spot in about a minute — costochondritis at two junctions — and explained why every heart test had been normal. One injection later, the pain was gone.”

★★★★★

“After shingles the rash healed but the burning never left. Eighteen months of gabapentin from my GP with no real plan. A nerve block confirmed exactly which nerve it was, and cryoablation gave me my first pain-free months in two years.”

Post-herpetic intercostal neuralgia · verified review
★★★★★

“Every time I bent over or ate a big meal I got a deep ache at the bottom of my breastbone. Gastroscopy normal, ultrasound normal, told it was probably reflux. It was xiphoid syndrome — an injection settled it, and I finally knew what I was dealing with.”

Mr Marco Scarci

MD(Hons) · FRCS(Eng) · FCCP · FACS · FEBTS · Consultant Thoracic Surgeon, Imperial College Healthcare NHS Trust

Unexplained chest wall pain sits in a no-man’s-land of modern medicine: cardiology excludes the heart, gastroenterology excludes the stomach, and nobody owns what remains. Mr Scarci has spent over two decades owning exactly that territory — the muscles, cartilage junctions, nerves and bones of the chest wall, and the systematic examination that identifies which of them is the source.

He performs every examination personally, carries out any injections and procedures himself, and follows your recovery through — the same surgeon from first consultation to discharge.

Common questions

Chest wall pain — what patients ask

How do I know it's not my heart?

You don't — until it has been checked, which is why new chest pain should always have cardiac assessment first, and why crushing central pain, breathlessness or pain radiating to the jaw or arm means 999, not an outpatient clinic. Most patients arriving here have already had normal cardiac tests. That is the right order: heart first, then a proper answer for the pain that remains — because “it isn't your heart” is a relief, not a diagnosis.

What is costochondritis, and how long does it last?

Inflammation of the cartilage joining the ribs to the breastbone — tender to the touch at specific points, worse with deep breaths and certain movements. Most cases settle within weeks to a few months with anti-inflammatories and activity adjustment. When it persists or keeps recurring, the job is to confirm the diagnosis is actually right — long-lasting “costochondritis” is sometimes a slipping rib, a nerve problem or a xiphoid syndrome in disguise.

What is xiphoid syndrome?

Pain and tenderness centred on the xiphisternum — the small cartilage tip at the bottom of the breastbone. It can follow trauma, vigorous exercise, or arise on its own, and is aggravated by bending, large meals or tight clothing. Treatment ranges from reassurance and anti-inflammatories to local injection, and in persistent, confirmed cases, surgical removal of the xiphoid (xiphoidectomy).

Why do my scans keep coming back normal?

Because several of the most common chest wall diagnoses are clinical, not radiological: costochondritis, intercostal neuralgia, slipping rib syndrome and xiphoid syndrome are all made — or missed — on examination. Scans exclude other causes; they rarely provide the answer by themselves. The pathway here starts with a detailed history and a structured physical examination, and uses imaging and diagnostic nerve blocks to confirm, not to fish.

Can a rib fracture that healed years ago still cause pain?

Yes. Malunion (healing in a poor position), nonunion (never fully healing), and intercostal nerve damage can all leave pain long after the bone was declared healed — and all three are identifiable and treatable, from nerve blocks and cryoablation to surgical refixation. Old pain is not automatically permanent pain.

Is this covered by insurance?

Yes — assessment and treatment of chest wall pain, including diagnostic nerve blocks and any surgery, is recognised by the major UK insurers, and the practice manages authorisation for you. Self-pay patients receive written estimates in advance, and remote consultations are available to review your history and imaging before you travel.

“All your tests are normal” is not a diagnosis.

A structured chest wall assessment finds the cause behind most “unexplained” rib and chest pain — and pairs it with treatment that actually matches. You leave with an answer and a plan.
