Should I be worried?

[SFR]

About a month ago I noticed a pea sized lump on my left testicle. It is hard and not tender to touch. I am pretty sure that it has not grown. About a week ago I started to experience lower back stiffness/back spasms. These have since passed. I've had these before so these might just me having more back spasms. Other than that I've had no pain in my groin area. I am going to make an appt. with a urologist this week...but has anyone else had something similar? Should be I be nervous/concerned prior to my visit? My father died from lymphoma as well as grandparent from another type of cancer, so cancer has been in my family. Any advice/info/suggestions are welcome.
Thanks

It's good that you're having that lump checked out, and you'll probably want to have an ultrasound of the testicle. It may well turn out to be nothing serious, but it's best to be safe.

I notice you wrote it may well turn out to be nothing serious, is this a common occurence what I describe?

The "pea-sized lump" sounds like the classic description of testicular cancer. However, that is relatively rare, while cysts, which are collections of fluid rather than solid masses, are much more common.

Do my other symptons, like the back stiffness and the fact that I was sick about 2 weeks ago with a fever and general feeling of lowsiness...and now have a cold and small cough all add up with my lump to very specific type symptons? I'm just trying to get the most info from others as much as possible. Thanks

I'd say everything but the lump is probably just coincidental.
