Hello Thanks for query . Multiple painless bumps in genital area and scrotum are multile Sebaceous Cysts . Genital skin is rich in sebaceous glands hence more prone to get these cyst due to accumulation of sebum resulting from the blockage of the opening of the ducts on surface of 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 ind if he thinks to get excised get them excised in Toto . This is a simple surgery done under local anaesthesia as a out patient procedure and offers permanent cure. Dr.Patil.
