Thanks for your query.Based on the facts that you have posted it appears that you have multiple sebaceous cysts over scrotum
The scrotal skin is rich in sebaceous glands and hence prone to get more sebaceous cyst due to accumulation of sebum beneath the skin.
Normally they fade away without treatment however they need to be treated if increase in size or get infected.
Please consult qualified General Surgeon
for clinical evaluation and further treatment.
Please avoid peeling off hair from scrotal skin ad ensure proper hygiene by cleaning the genitals and scrotum with warm water twice daily.
