If the pain is mild, you can take diclofenac sodium capsules or ibuprofen extended-release capsules, celecoxib capsules and other drugs, which can relieve the pain caused by stones to varying degrees and last for a relatively long time. However, if there is acute pain or if the pain is not relieved after oral medication, intramuscular injection of pain medication is needed, commonly used drugs include dulcolax injection, morphine injection, etc. Intramuscular injection can immediately relieve the renal colic caused by stones, but after intramuscular injection, side effects such as nausea, vomiting or dizziness may occur. In addition, intramuscular injection of tramadol or brucizine hydrochloride can also be given, which has a slightly lower pain relief effect than dulcolax and morphine, about half of the analgesic effect, but hardly produces any addiction and can be repeatedly used within a short period of time.
