In clinical practice, we often find that the body speaks in a “referred” language. A patient may come in complaining of a deep, persistent ache in their right shoulder, assuming it is a muscle strain, when the root cause actually lies within the Liver system.
Watch: Why the Liver Causes Shoulder Pain
Understanding the “why” behind this connection is a vital part of our integrated diagnostic approach.
The Anatomy of Referred Pain
The liver itself has no pain receptors, meaning early-stage changes often go undetected because there is no localized pain [00:00]. However, as the liver sits just beneath the right ribs and the diaphragm, its growth can affect the surrounding network of nerves.
The key connection is the Right Phrenic Nerve [01:05]:
- This long nerve travels from the diaphragm, up through the chest and neck, and connects to the right shoulder.
- When the liver capsule is stretched or the diaphragm is irritated, the phrenic nerve sends a signal that the brain often misinterprets as pain coming from the shoulder [01:14].
- This typically feels like a constant deep ache or a “pulling” sensation in the right shoulder [01:23].
5 Early Warning Signs to Monitor
Beyond shoulder pain, it is important to look at the body as a whole. Seek a professional assessment if you notice:
- Persistent right shoulder pain (unrelated to injury) [01:30].
- Jaundice (yellowing of the skin or eyes).
- Mild pain in the upper right abdomen.
- Loss of appetite.
- Unexplained weight loss.
The Integrated Diagnostic Path
At our clinic, we recognise these signals as a call for deeper investigation. If these symptoms are present, we recommend working with your GP to organise:
- A Liver Ultrasound: To visualize any changes in the organ’s structure.
- AFP Blood Test: To check for Alpha-fetoprotein, a marker often elevated in liver pathology [02:06].
