Final answer:
Testicular torsion is suspected when scrotal pain is not relieved by elevation, as this is a condition where the spermatic cord twists and induces pain that does not improve with scrotal elevation unlike in epididymitis.
Step-by-step explanation:
When a kid has scrotal pain that is not relieved by elevation, one might suspect testicular torsion. This condition involves the twisting of the spermatic cord, which causes a reduced blood flow to the testicle. It differs from epididymitis, which typically presents with inflammation and can be associated with sexually transmitted infections. Unlike epididymitis, testicular torsion is a surgical emergency and requires immediate intervention to save the testicle. The pain associated with epididymitis may be alleviated by scrotal elevation, but this is not the case with testicular torsion, thus the latter condition is highly probable given the lack of improvement with elevation.
