Hello dear, Thank you for your contact to health care magic. I read and understand your concern. I am Dr Arun Tank answering your concern. I suspect there is infection caused by resistant organisms, as there treatment is not responding to the standard therapy. I advice you should take the urine culture sensitivity done. This will guide you regarding organisms and its sensitivity pattern. Taking treatment according to this report cures your every problems like burning, pain, sensitivity while utinating everything. Also drink lots of water as it can also help flush bacteria out of urinary tract. Please maintain hygiene as it is equally important as taking antibiotics. Phynazopyridine is urinary analgesics which help you prevent infection. I will be happy to answer your further concern on bit.ly/DrArun. Please hit thank you for me if you are helped.
