Presence of fluid in testicle is called Hydrocele
2. Infection e.g. Filarial infection
3. Inflammation e.g. Orchitis
1. Analgesics such as paracetamol
2. Avoid wearing tight-fitting underwear
3. Treatment of underlying cause
4. Surgery- hydrocelectomy to drain out the fluid.
So...it will be better to consult an Urologist
to find out the exact cause.
So that necessary management steps could be taken.
Wishing you a Good Health. Let me know if I need to clarify further.
Thanks & take care.
