Kidney stones can cause significant pain despite their small size. Factors such as hydration, diet, and certain medical conditions can affect the risk of developing them. A board-certified physician, Dr. Rhea Rogers, explains that kidney stones are hard mineral and salt deposits that form in the kidneys and can block small tubes in the body, leading to excruciating pain.

A gerontologist, Sam Cradduck, who has had four kidney stones, describes the pain as comparable to putting a jagged stone through a straw. Dr. Rogers provides more information on what causes kidney stones and how to lower the risk.
