Patient's question:
A lump has grown behind my left testicle, it's very soft and has been there for several years~ I don't know what it is, and there's nothing on the right side. What could this be?Additional question: Hello, if it's an epididymis, why is it very noticeable on one side but not visible on the other from the outside? Thank you
Doctor's answer:
Hello: This is the epididymis. If there is no tenderness, treatment is not necessary
