Experts are always like to use analogies to express ideas about medical topics because the verbosity associated with the medical field is usually complex. They think the yellow balloon and purple balloon analogy might explain the premise of how to diagnose the cause of pain and why one should take the colorful medical balloon approach to identify the cause of pain.
When a person is in pain, they usually go to the hospital and see a doctor who wants an X-ray or an MRI, or both. Structural abnormalities such as herniated disc, stenosis, arthritis, meniscus tear, or rotator cuff tear were identified. This is the basis for diagnosing what is causing a person's pain.

The problem with this method is that research shows that nearly as many people without pain can have the same findings as those who experience pain in about the same percentage. Much of this research now calls into question the use of these diagnostic tests to compare causes of pain.
You can see the suspected cause of pain found in this diagnostic test as a yellow balloon. And practitioners who use this method to diagnose the cause of pain are only trained to identify the yellow balloon.
You can see that if the cause of the pain is muscle tension, muscle weakness, muscle spasms, or muscle pain, it doesn't show up on this type of test. This cause can be seen as a purple bubble. Whether you see an orthopedist, chiropractor, neurologist, or even most physical therapists, they are simply trained in the art of finding and treating the cause of jaundice.
