This is a four answer multiple selection question with a mixture of investigations and management options. The patient is presenting with sub-acute slowly worsening scrotal pain, mild dysuria without discharge, a low grade temperature, and unilateral localised testicular tenderness. The most likely diagnosis is epididymo-orchitis. The subacute presentation and patient age makes an acute testicular torsion unlikely. Whilst a sexually transmitted infection is a less likely cause, it cannot be excluded from the history. His pain is not severe.
Therefore, correct answers relate to rational initial investigation to determine the causative organism and provision of simple analgesia. Antibiotics can be initiated once the causative organism is known. There is no imminent emergency to warrant urgent referral.
