Unexplained Chest Pain
When the Heart Has Been Checked & It Is Still There

Chest pain with a cardiac cause ruled out is most commonly caused by the chest wall — the ribs, cartilage, muscles, or thoracic outlet. These are real, identifiable, and treatable conditions. They are often missed because the focus goes straight to the heart. Dr Lawrence Okiror, Consultant Thoracic and Robotic Surgeon (GMC 6150382), assesses and treats chest wall causes at London Bridge Hospital. Most patients leave the first appointment with a clear diagnosis. Private appointments within 2–3 days. No GP referral required.

The Chest Wall Is Commonly Missed

When chest pain is assessed, the ribs, cartilage, muscles, and nerves of the chest wall are frequently overlooked. A thoracic surgeon examines these structures specifically and can usually identify the cause at the first consultation.

Most Causes Are Treatable

Slipped rib syndrome, costochondritis, rib fractures, and thoracic outlet syndrome are all manageable conditions. Many respond to non-surgical treatment. Where surgery is needed, results are consistently good.

Cardiac Note

If you have chest pain with breathlessness, sweating, or pain radiating to the arm or jaw, call 999 or go to A&E immediately. A thoracic surgeon assesses chest wall causes — cardiac assessment should be done by a cardiologist first.

What Is Actually
Causing the Pain?

These are the most common chest wall causes of persistent or unexplained chest pain. All are treatable and diagnosable at the first specialist consultation.

Slipped Rib Syndrome

One of the lower ribs moves excessively, catching on surrounding structures and causing a sharp, catching pain in the lower chest or upper abdomen. Frequently missed and attributed to reflux or back pain. Diagnosis is usually clinical. Surgical treatment gives consistently good results. Slipped rib syndrome →

Costochondritis & Tietze Syndrome

Inflammation where the ribs join the cartilage connecting them to the breastbone. Causes localised tenderness worsened by movement or pressure. Common and usually responds well to anti-inflammatory treatment. Surgery is rarely needed.

Thoracic Outlet Syndrome

Compression of nerves or blood vessels between the collarbone and first rib. Causes arm, neck, shoulder, and sometimes chest pain. Often misdiagnosed as rotator cuff or cervical spine disease. Dr Okiror offers robotic keyhole decompression — one of very few surgeons in the UK to do so. TOS →

Rib Fractures & Pleural Pain

A rib fracture causes persistent pain worse with breathing and movement. Most heal with time. Pleurisy — inflammation of the lung lining — causes sharp, stabbing pain worse with breathing. CT scan identifies both. Pleural disease →

My heart has been checked and is fine. Why do I still have chest pain?
Because the chest wall is a very common source of pain that is frequently overlooked. The ribs, cartilage, chest wall muscles, and nerves can all cause significant, persistent pain that has nothing to do with the heart. A thoracic surgeon examines these structures specifically and can usually identify the cause at the first consultation.
What is slipped rib syndrome?
One of the lower ribs moves excessively, catching on surrounding structures and causing a sharp, catching pain in the lower chest or upper abdomen. Frequently missed and attributed to reflux or back pain. The diagnosis is usually clinical. Surgical treatment gives consistently good results. Slipped rib page →
Can thoracic outlet syndrome cause chest pain?
Yes. TOS — compression between the collarbone and first rib — causes arm, neck, and shoulder symptoms but can also cause chest pain. Often misdiagnosed as a rotator cuff or cervical spine problem. Dr Okiror offers robotic keyhole decompression — one of very few surgeons in the UK to do so. TOS page →
What is costochondritis?
Inflammation where the ribs join the cartilage connecting them to the breastbone. Localised tenderness worsened by movement or pressure. Common and usually responds to anti-inflammatory treatment. Tietze syndrome is similar with visible swelling. Neither usually needs surgery.
Will I need surgery?
Not necessarily. Many chest wall conditions respond to non-surgical treatment. Surgery is considered where conservative treatment has not resolved the problem and the anatomy is clearly surgical. Dr Okiror gives an honest assessment of which applies in your case.
Do I need a GP referral?
No. Private appointments within 2–3 days at London Bridge Hospital. Bring any existing imaging. New consultations from £250. Most major insurers accepted. Second opinions also available.

Chest pain without a clear cause
usually has one. It just hasn’t been found yet.

No GP referral required. Private appointments at London Bridge Hospital within 2–3 days. Dr Okiror will examine the chest wall specifically and give you a clear answer and a clear plan.
