lump from Ball pumping?

[luv2pump]

Ok never fun to topic a pumping problem but maybe someones had this.
Ive pumped for over 16 yrs. max pumped balls past 5yrs.
Rode my bicycle 20 miles 3 days ago and noticed a walnut size lump on my undercarriage at back end of ball sack. Didnt pump that day.
Its sore like a cist. Tried ball pumping today & its right where tube meets behind balls sack;(
I wonder if ball pumping caught up to me or its from bicycle seat.
Anyone had this problem?
I AM going to doc but have 4 week wait.

Maybe it has something to do with the long bike ride.

I hope thats the case. Id hate to give up ball pumping. We know how awesum that is plus it sure helps preventing the balls from geting sucked in penis tube.
Thanks for the reply Pipefitter.

If that lump is still there after two weeks, please have your doctor to check it. He'll probably x-ray it. Lots of testicular cancer starts that way and left untreated you could loose you balls, or even you life. Check it out and be safe. I've pumped that long also but never had that particular swelling or lump. Doctors don't need too know about your pumping. They don't even care about you size. It could be something as simple as an inflamed prostate--all treatable. Check it out especially if you see any discoloration in urine or any burning while peeing.
