Been experiencing a dull achy feeling in my testicles for over 3 weeks now. I was evaluated by an ER doctor and tested negative for any STIs or other infections. Had an ultrasound and there was nothing major found. They did find a very small varicocele. I consulted a urologist who told me that the varicocele was not large enough to be causing the pain and the only reason they knew I had one is from the ultrasound. He told me that my testicles appear completely normal. He said he found a small amount of blood in my urine and I had been experiencing some back pain, so he sent me for a CT scan to check for kidney stones. The CT scan came back normal. I workout a lot, so my main question is, could my back being out of alignment pinch nerves to my testicles? Any help or information would be greatly appreciated. Thank you.
