I have a cyst / lump above my left epididymis, it gets bigger if I pump my balls. It is hard and moves with the spermatic cord. I have no problems or aches with it except that it is uncomfortable to see when it gets bigger. It clearly visible when the ball sack is relaxed and I sit down on the toilet.
I feel something similar on the right ball but it is not moable and is what I suspect the epididymis. If I do not pump for a while, it is smaller than a peanut, but if I pump, it will be more than twice as big.
It also appears to be some type of hydrocele under the epididymis as it appears to collect some fluid there. Ask me if something is unclear. I can also try posts a picture later if needed.
