###Human: What could this pea sized lump around my scrotum be? ###Assistant: Hello. You have had a blunt trauma to your scrotum almost a week back and since then have had a decrease in the swelling and no urinary complaints which are good signs. Was there ever any blood in the urine immediately after the incident? From your description, it appears that what you have is a scrotal hematoma which is resolving gradually. So you need to worry. All you would need is some scrotal elevation which will ease pain and swelling. But I would still advise you to visit your urologist to make sure the pain is just in the scrotum and not involved the testes, which is not possible without a clinical exam.
