and to know the infective organism and its senstivity you need to get a routine urine exam and a culture and senstivity done, according to that you will have to take a course of antibiotics, do not wait till 12 feb for the treatment start. The same antibiotics may not be effective again so it is best to start those same tablets after you have given a urine sample for testing and if there is change in antibiotic senstivity then change the drug accordingly or continue with the same. In the meanwhile you can take plenty of fluids ,syrup citralka to reduce the burning sensation. Take care.
