Medical tests
They include X-ray, an ultrasound, electrical studies, and others that will confirm a doctor’s findings. The most common is X-rays, which clearly picture the bony structures and help doctors identify injuries to the articulation’s bony part. Magnetic resonance and ultrasound are typically used when doctors need to evaluate the soft tissues (muscles and ligaments, mainly). An electrical study such as EMG can be useful to assess nerve function and how the muscle responds to it. But sometimes these studies are not enough to diagnose the disease, and your doctor may require a more invasive procedure such as arthroscopy, in which a tiny camera is inserted inside the articulation to see live what is going on.
