When kidney stones occur, there are often significant pain symptoms. This is mainly due to the smaller stones in the kidney moving within the kidney or falling into the ureter, stimulating the ureter wall, causing ureteral spasms and subsequent pain. The pain usually appears suddenly and can be very intense. In such cases, it is necessary to go to the hospital promptly for spasm relief and pain treatment. Medications such as scopolamine, atropine, or tramadol can be used for pain relief. If necessary, scopolamine may need to be administered intravenously. (Specific medications should be used under the guidance of a physician.)
