Hello, Welcome to healthcare magic. I understand from your query that your son has an itchy rash in his groin. The most common cause for itchy rash in the groin area is a fungal infection called tinea cruris or jock itch. Rovate is steroid which will not help him. Infact, it can worsen the condition. He can benefit from applying a cream containing 1 % Terbinafine twice a day for 3 weeks. He could also take weekly dosage of fluconazole which has to be prescribed by a doctor. For itching, he can take an antihistamine like levocetrizine at bedtime. He should keep the area dry. He should wear loose undergarments preferably boxer shorts so that the area is well aerated. Hope this helps you. Take care.
