For at least 5 yrs I have periodically felt a slight pain in the epididymis region of my right testicle. The pain is not universal and seems to be isolated to the vein structures in the region connecting the testicle to epididymis. Pain exists right at the point where the lower epididymis connects to the testicle and also exists in the tail of the epididymis.
During routine checks,there is no apparent pain or discomfort to the testicle and there are no "lumps or bumps" on the testicle itself. If I really feel around and run my fingers up and down the epididymis, however, there is sometimes a sharp pinching sensation where the epidiymis connects to the testicle and the veins/arteries in the area sometimes seem sensitive. The pain's sharpness will subside if I massage a few seconds. In the morning, or while lying in bed, I rarely experience anything it seems to only act up once I am up and active. It seems to coincide with athletic activity, or following athletic activity. Sometimes, while exercising, if I suddenly make a lateral lunge with my right leg, I will feel a slight twinge. Once the initial twinge has occured, however, it doesn't happen again -- almost as if I stretched it out. I will periodically feel a slight twinge if I bend down while wearing jeans and pressure is applied to the scrotal region.
I am 39, caucasian, healthy and was born with an undescended right testicle (which was repaired at birth).
