Please help me

I went to the urgent care for a UTI and they gave me antibiotics. It started hurting again a few days after pills were gone so they gave me a different kind. Now they're saying nothing grew in the culture so I need to come in again.
The medicine they gave me that numbs the pain there isn't working. It's burns so bad I'm sobbing right now. I can't go to the doctor because it's 1:30 am. What are fast ways to releive  the pain until I can go to the doctor? I have cried from pain in years.
