If you're looking for natural cures for painful kidney stones, there are some apple cider vinegar-based remedies that you can try.

What are kidney stones?
Kidney stones form when minerals, like calcium, oxalate, and uric acid in urine become concentrated. These minerals crystallize, and they grow into larger masses or stones that can make their way through your urinary tract.

Kidney stones can get stuck somewhere. When these stones block the flow of urine, they can cause pain. Most stones occur when calcium combines with either oxalate or phosphorous. Kidney stones can also form from uric acid, which forms as your body metabolizes protein.

Kidney stones cause discomfort and pain in a person's stomach, groin, or lower back. Unless you want to take medications or undergo surgery to remove kidney stones, you can try simple home remedies that include apple cider vinegar (ACV).
