thats strange because your kidneys are round your back burning pain dsnt sound gud i use to drink it every day for like 6 months hvnt had a kidney infection since i think endo was causing mine as it was in my bladder they found blood in my urine and my friend lost her kidney due to endo being all rapped round it she had to have it removed so believe me its best to look after your kidneys and dont ignore anything i have no faith in doctors they told me my digestion was ibs withot even investigating anything
