It sounds like you may be developing hydrocele from your frequent cases of epididymitis. Epididymitis is an inflammation of the cord leads from the testicle toward the penis; this can occur from infectious and noninfectious causes. Most of the time it is infectious, and it requires adequate treatment with antibiotics to clear up. Sometimes, the infection can become chronic and can require a longer course of antibiotics. Sometimes, however, the epididymitis is recurrent and noninfectious; this is usually due to a structural problem, such as a blockage in the urethra or prostate.
You should see a urologist
to help sort out why you are having recurring cases of epididymitis. I say this because the hydrocele is probably just a reactive and inflammatory change that is produced from the recurring epididymitis. If this is the case, then you will not be able to satisfactorily treat the hydrocele until you have identified and treated the cause of the recurring epididymitis.
One the epididymitis is resolved, then surgical excision of the complete hydrocele cysts should resolve the problem for you. Start by talking to your urologist. If you do not have a urologist, your primary care doctor
can recommend one and make the referral for you.
