I have went to the doctor several times about my kidneys and they say my kidney function is fine but the constantly hurt. And my whole private parts hurts to. Burns when I pee and alot of times have to push it out. It feels like a constant sunburn inside where the kidneys are located. Always feels like I have to pee. I've went through antibiotics and azo pills and cranberry juice hasn't subsided in over 6 months. They say no kidney stones and no problems.?
