What is the classic sign of pain relieved by testicle elevation in epididymitis called?

The classic sign of pain relieved by testicle elevation in cases of epididymitis is known as Prehn's sign. This sign is used in clinical examination to differentiate epididymitis from testicular torsion. In epididymitis, elevating the affected testicle often alleviates the pain, which is indicative of inflammation of the epididymis. This response is due to the relief of tension on the affected structures and the decrease in pressure in the scrotum.

In contrast, testicular torsion would typically not show relief with elevation, as this condition usually involves a vascular emergency where the blood supply to the testicle is compromised. Recognizing Prehn’s sign is therefore crucial for healthcare professionals in providing appropriate and timely management based on the underlying cause of scrotal pain. Other terms mentioned in the options, such as rebound tenderness or McBurney's point, relate to different clinical scenarios and would not be applicable in the context of epididymitis.
