What Passing a Kidney Stone Feels Like

Summary

Passing a kidney stone can cause severe, intermittent pain in the flank or back that may radiate to the groin. Additional symptoms include nausea, vomiting, blood in the urine, and increased urgency or frequency of urination. The timeline for passage depends on the stone’s size, shape, and location, with smaller stones under five millimeters and those closer to the bladder passing more easily. Supportive measures include staying well-hydrated, taking pain medications, using heat therapy, and sometimes taking medications like Tamsulosin to relax the ureter. If the stone does not pass within four to six weeks, or if symptoms worsen with fever, vomiting, or urinary blockage, urgent medical attention is needed. Understanding what it feels like helps patients anticipate and manage this process safely.
