I have one testicle and for the past month and a half I have been having pain under my testicle. I sometimes force to pee just to get it out and force to do #2. I am wondering if I have strain a vein or something. I've stopped doing this but the pain persist. It comes on mostly at nights and I toss and turn all night. I take Advil and it works for while but by the time it kicks in its time to get up for work. Please tell me what this problem sounds like to you. My testicle is fine just the constant pain thats underneath.
