I am Dr. Arun and will be helping you today.
I am sorry that your question was unanswered for long.
A long course of antibiotics may cause yeast infection. But instead of bladder (termed cystitis); vagina is more commonly involved as it changes the normal bacterial flora of the area. So there is a white vaginal discharge from vagina (cottage cheese like / vaginitis). So if you do not have this symptom; it is likely to be a bladder infection (with the frequency and pressure after urination which are not uncommon symptoms). This cystitis (bladder infection; can be bacterial, which is far commoner or yeast which is not usual) can be confirmed by;
1) Urine culture for the pyogenic bacteria
2) Urine culture for yeast.
That would determine the further course of treatment.
Meanwhile following measures would be helpful:
b) Cranberry juice
c) Plenty of liquids.
d) Pyridium / Azo; which needs to be taken for three days; is available over the counter and would resolve your symptoms.
Please feel free for your follow up questions.
I would be happy to assist you further, if you need any more information.
Thanks for using Just Answer.
