A year ago I went to a neurologist who diagnosed me with a cyst on the top of my right testicle. He believed it to be non cancerous, and from what I understood would eventually pass. A year later, I experience no pain, but do feel the presence of the cyst there. The only side-effect is that at times the testicle with the cyst does not hang down normal length but rather it clings to the body. Should I be worried?
