Final answer:
Prehn's sign refers to the relief of scrotal pain with elevation and is associated with epididymitis. It is distinct from symptoms of orchitis or prostatitis.
Step-by-step explanation:
The relief of pain with scrotal elevation is known as Prehn's sign. This clinical sign is often associated with epididymitis, an inflammation of the epididymis, which can cause pain in the scrotum, testicles, and groin. Scrotal elevation can alleviate pain for some patients suffering from epididymitis. It's important to distinguish this from symptoms of other conditions like orchitis, which is the inflammation of the testicle, often following an infection from the epididymis, or prostatitis, an inflammation of the prostate gland.
