Male health question: I’ve noticed the epididymis on my left testicle is larger and more sensitive than on my right?

I also have a very small cyst on the back of the same testicle, about halfway down. It’s about the size of a grain of rice and I’ve had it for a few months. It doesn’t really hurt, but every now and then I’ll feel some very mild pain down there. It’s not severe. On a scale from 1-10 it would maybe be a 2, and it’s not persistent. Is there some connection between the cyst and the larger, more sensitive epididymis? I find it weird how the one with the cyst has the larger epididymis. The epididymis on my left testicle is maybe twice as large than the one on my right. Long story short: am I dying?
