Need to ascertain the exact nature
Thanks for your query.
A swelling in the scrotum may be because of various reasons. It may be a hydrocele
(fluid in a sac), varicocele
(engorged blood vessels), hernia or even cancer. As it is persisting for 5 years, cancer is unlikely.
You need to get an ultrasound
of the scrotum to ascertain the exact cause. Treatment depends on the cause. Drainage
may be feasible if it is a fluid collection. Surgery may also be required.
Hope I have answered your query. I will be available to answer further followup queries, if any.
