<s>[INST] What can a mild sharp pain in a person s back, about waist-high on the right be from? I am female, 54, overweight. It started Saturday evening. It s not severe, but it s there. I can still eat, drink, walk, stand, go to the bathroom, and don t feel nauseous. It s constant and is not brought on by anything I am doing. I read about a gallbladder attack, but the symptoms don t match up completely. [/INST] Hi Hope this message finds you in good health.I have gone through your query in detail and see that you may either be having a fibromyositis of the back muscles or may be a referred pain from a abdominal pathology,most probably a kidney stone.You can take muscle relaxants and apply local gel with hot fomentation.If this does not help,then you should get a abdominal ultrasound done.Do not lift anything heavy .Avoid bending forward.I Hope your query has been answeredBest Regards. </s>
