I am 58 years old. I was having a calculus of 4 mm in my bladder. Yesterday it moved out while passing urine. After that I am having severe back and centre stomach pain. And also continues loose motion. I took ciplox tz and lm has stopped. I tested urine and blood but no infection. Two days back I ate barotta and egg curry at night. That didn't get digested. Now the pain is untolerable. The doctor advised to take plenty of oral fluids. Please advise.
