No UTI.! Just bladder pressure

Brooklyn

So I had a urine culture done that showed a bacteria that was resistant to most antibiotics. But sensitive to Bactrim! I finished the 7 days. I’m still having some pressure. Took another culture and bacteria is gone and I no longer have a UTI. So my gynecologist wants me to follow up with a Urologist. I still feel a pressure in the bladder that makes me believe that I have to urinate all day. I don’t know what to do and I’m nervous. Also CT scan was normal.
