Hello there,,,,well there are multiple causes for backpain,,,from simple muscle spasm to more complex problems like stenosis or prolapse disc... Also the history of your pain is necessary,,,like how did it start,type of pain,,,is the pain in back region or you get tingling and numbness also in the legs....various causes needs to be ruled out......also sometime kidney stones cause a typical back pain (waist line) so you need to check that as well.
