not sure that I have this...but urine has strong odor and is dark yellow. finding tiny particles floating in it. Hurting in groin and butt and upper thighs...hurts to sit for a long time. urinate alot . the past sixmonths I get that leg,butt,groin pain for one day then the next day there is soar (not open) around where I urinate and it lasts about 3 days then goes away until about 2 months later when it starts all over again. They are painful and are always near the same spot. i have been to 2 different dr\'s in 8 mos and they check for bladder and kidney problems, but nothing. i told them that i have noticed this change in the urine in just the past year or so, but they say it is normal. have you ever heard of anything like this?
