Hi Sir, I understand your query and concern. As per your clinical description of pain,it usually points to renal stone located somewhere in the lower ureter leading to urinary tract infections.For this you need to have an ultrasound abdomen and CT scan of the abdomen for accurate assessment.I advise you to have Tab Tramadol and Tab.Pantop 40 mg,a course of antibiotic like tab.norflox 400 mg for 5 days taken under medical prescription to control this pain.Further expert management depends on the outcome of the CT scan result.If the size of stone is more than 5 cm then depending on the location of stone Extra corporeal lithotropsy can be done.Meanwhile you need to take soft and less spicy foods.Drink 3-4 litres of water everyday.Fruits,fruit juices,vegetable salads,soups should be taken. Post your further queries if any. Thank you
