Hi, thanks for posting your concern in the HCM. I think you may have got recurrent UTI, in a more complicated status. Renal or ureteric stone should also be ruled out, because they also produce similar symptoms. In case you have a complicated UTI or renal/ ureteric stone or pyelonephritis, you may need injectable antibiotics. If there is a stone, surgical treatments may be needed depending upon the stone size and renal condition. I think you should consult your local urologist at the earliest or should visit the ER of nearest hospital as soon as possible. You may need in patient treatment. The following investigations may also be needed- Blood- complete blood count, urea, creatinine, CRP, electrolytes Urine- Routine examination and culture/sensitivity Xray and/ or USG of the KUB region. You should not start any other antibiotic until your doctor tells you to do so, before sending the urine sample for culture/sensitivity testing. Regarding the pain, you may have Drotin DS tablet as and when required for the time being and consult your local urologist today if possible. Take 3 lit. of oral fluid until your doctor tells otherwise. For any further query you may write back to me directly. Regards, Dr. Kaushik
