Kidney infection

I had a uti back in November I got medicine for it and finished the full dose... fast forward to about 2 weeks ago i started having pain in my right side it’s always on my right side so I upped my intake in water the pain went away now my back and stomach hurts I almost threw up at work from the pain😣 I went to the er last night it was packed I waited about 3 and a half hours to be seen I ended up going home! Is there anywhere else like urgent care or somewhere I can go to get seen??
