I have kidney pain what it cut be?i have recently stop drinking soda and star drinking water. when start drinking water is when the pain start.

See a doctor: Congratulations on switching from soda to water- that will have many benefits! kidney pain is usually caused by either kidney stones or a kidney infection, though often pain in the kidney area is not from the kidneys at all but from the muscles in the area of the kidneys (this is likely if the pain is affected by motion or position). Please see a doctor for evaluation & treatment.

See a doctor: If you have kidney stone in the past and it reoccur, you need to see a doctor. Your doctor can use radiology study to check the size and location of the stone. If necessary can use procedure to remove it.
