<s>[INST] I have treated UTI with different drug for over 2 weeks . the last drug was ornilox and it helped. It was prescribed for only five day. I started taking on the last 2 days of taking taxim-o. This last drug helped and the pain went away the last day i took it but after 3 days the terrible pain came back. Previoulsy to taking any drug a culture and sensitivity was done. It found the common bacteria e. coli in teh urine +++++. Now I am hurting very much. [/INST] HelloWelcome to Chat Doctor, Your history and symptoms suggests that you have UTI secondary to Bladder Neck Obstruction. Bladder Neck Obstructions causes incomplete emptying of bladder during micturition resulting in to some amount of urine remaining in bladder. This stagnated urine IDs the source of infection and getting UTI. Taking antibiotics will solve your problem temporarily. I would advise you go for endoscopic incision of bladder neck (Bladder Neck Incision) so that your bladder neck will remain wide open and help in emptying bladder completely during every micturition, and there by prevent frequent episodes of UTI. This is simple surgery you need to consult the urologist for opinion and treatment. Thank you </s>
