Frequently Asked Questions

What food should be avoided for kidney stones?

Avoid Beets, chocolate, spinach, rhubarb, tea, and most nuts are rich in oxalate, which can contribute to kidney stones. If you suffer from stones, your doctor may advise you to avoid these foods or to consume them in smaller amounts.

Where in your back do you feel kidney pain?

Kidney pain is felt higher and deeper in your body than back pain. You may feel it in the upper half of your back, not the lower part. Unlike back discomfort, it's felt on one or both sides, usually under your rib cage. It's often constant.

Why is kidney pain worse at night?

Usually, people with kidney stones have more pain in the late night and early morning. This is since people normally urinate less during the late night and early morning and at this time the ureter remains constricted.
