Once the kidney stones grow too large, they can cause much pain. Some people are not even able to move correctly because of their kidney stones. You must opt for painkillers while treating kidney stones. You should take medicines that have salts, such as acetaminophen, ibuprofen, or naproxen. Some common examples of these medicine salts are Advil, Motrin IB, Tylenol, etc. Alpha-blockers are known for relaxing the muscles of an individual. These blockers will help the body to naturally pass out kidney stones. Some doctors even like to prescribe alpha-blockers to their patients.
