Dear Dr.,
I would like to know if my illness can be cured. I have been tortured by it for two years. When I do not drink water, my urethra would be painful. I have already taken lots of medicine, such as Gatifloxacin Tequin and Levofloxacin, but they all failed to take effect.
Please help me.

previous diagnosis and result: had a urinary tract infection
accessory examination: made a cystoscopy
