Having ureteral stones often leads to renal colic, which is a more severe pain and patients are usually advised to seek prompt medical attention. If the pain is not very severe, you can go to a nearby pharmacy to buy effective analgesic medications such as Saxifrage, Cilostro, etc. for analgesic treatment. If the pain is more intense, it is recommended to go to the hospital for analgesic treatment with stronger painkillers and, if necessary, antispasmodic medications, like 6542 to help decongest smooth muscles. The most important thing is to release the obstruction caused by stones in order to solve the problem of renal colic from the root.
