Hi, I am 39 y male from Australia and I have been having problems with my renal system for the last 3-4 months , I am unable to pass normal flow of urine and its very less compared to the fluid intake ,Some days I have more urge to go more frequently with large amounts of urine and have persistent kidney pains and back pains . I have been to my g.p and othe doctors too have had numerious tests but nothing has been diagnosed . Now this may sound strange but I have a doubt that my partner is giving me something as we are having marriage problems and I have a fair bit of property in my name after my parents but I cant discuss this with her as it may create more problems in my marriage and I don't have any proof of it , my question is is there any kind of chemical or toxin that can be responsible for all this ? please advise
