Hello and thanks for your query. I shall make an effort to provide you with good professional recommendations specific to your questions. There are many causes of scrotal swelling, but based on the information provided be you it appears to me that it may be a hydrocele. A hydrocele is a sac filled with fluid that forms around a testicle. To diagnose a hydrocele, your doctor will perform a physical exam. If you have a hydrocele, your scrotum will be swollen, but you won’t have any pain. Your doctor won’t be able to feel your testicle through the fluid-filled sac. To aid diagnosis, your doctor may shine a light through the scrotum. This is called transillumination. It allows your doctor to determine if there is fluid in the scrotum. If fluid is present, the scrotum will allow light transmission, and the scrotum will appear to light up. So I advice you to see your doctor for examination and diagnosis, based on that the doctor will consider the next best line of management. Yet again, I duly appreciate your query to me, I do hope that have found something useful to help you and I shall be glad to answer any further apprehensions. Sincerely,
