Hydrocele is a common cause of scrotal swelling caused by a patent space in the tunica vaginalis. The treatment is often conservative unless the hydrocele size is big leading to discomfort or difficulty in walking. This is often managed with drainage. This can also recur where pathological conditions like hypoproteinemia, filarial infections, or pelvic cavity malignancies have to be ruled out. If the cause is idiopathic, surgical procedures like sclerotherapy or hydrocoelectomy may be indicated. It is best that you have this checked by your doctor for proper evaluation. Take care and do keep us posted.
