Thank you for your query at AskTheDoctor.com
I understand your concern.
Scrotal itching is mostly due to excessive sweating, or fungal infection.
Rarely even bacterial infections can present the same way associated with a tiny bump.
I will advise you to apply Clotrimazole ointment as well as Mupirocin ointment twice daily for 2 weeks on the affected spot. This will reduce the itching. You will need prescription for the same.
Hope this was helpful,
