So I was doing a self examination on my testicles and found two small lumps the size of a grain of rice on my left testicle. The lump is very soft and tender near the epididymis top part of the testicle. I went to the urologist he said there is no immediate worry or concern. However, I will be going to get a ultrasound on the area soon. I noticed that I been getting pain on my left groin area, with occasional small bursts of discomfort in the left testicle. What could this be?
