Hi ! Good morning. I am Dr Shareef answering your query. One of the common reason for such bumps in the scrotal skin is formation of multiple sebaceous cysts. This could give rise to itching as well. I would advise you not to scratch it to avoid infection in it. I would also advise you to see either a Dermatologist or a General Surgeon in your area to have a physical examination and deal with the condition after proper diagnosis which might not be possible with discussion on the net. I hope this information would help you in discussing with your family physician/treating doctor in solving this problem. Thanks for using the healthcare magic forum for your health query. Wishing you an early recovery. Dr Shareef.
