Although have kidney stone, but how is not painful to return a responsibility

The cause of pain in patients with kidney stones is usually related to the movement of the stones. Therefore, when patients with kidney stones do not feel pain, this may be because their stones are stable and do not move or incarcerate. Clinically, larger kidney stones tend to be stable. Although stones are present, they do not obstruct the urethra, or because the stones do not move and thus do not irritate the urethral mucosa, so patients do not feel significant pain. Small stones may cause pain in the lower abdomen or perineal area when they move. However, if they do not move, or if they move but do not irritate the urethral mucosa, they will not cause pain. It is important to note that even if kidney stones are found but do not feel pain, there may be other factors. Therefore, it is recommended that patients go to a regular hospital for treatment in case the condition worsens.
