Should I go back to ER update

I went into er they just sent me up to labor and delivery but I was feeling like I had a uti and having extreme pain front n back on my right side they did an ultrasound on my kidneys and they said I just have a really bad uti and it could spread to my kidney if not taken care of right away so they gave me antibiotics it’s been over 24 hours on the antibiotics and my pain hasn’t gotten any better and has moved higher up like under my ribs I’m so uncomfortable I’ve been throwing up my whole pregnancy on top of it which has only gotten worse and hurts so bad when I’m puking do I go back or just keep taking the antibiotics I’m just hesitant on going back because I have really bad ptsd from feeling my csection n having to be put to sleep so I’m already going in anxious n the inside of my arm is bruised badly from them not doing my iv right I’m just scared and in pain I’ve been missing work and I need to figure something out cause I can’t keep doing it 😫

They took my blood and sent me home I’m still in so much pain it was the same dr so he came and said well it’s not this we did this but said on my ultrasound that my right kidney was dilated but none of that was on paper work let alone anything about my ultrasound and he never brought that up to me they were very dismissive and seemed annoyed that I was there again so soon didn’t even offer to wheelchair me down from labor and delivery she just took out my iv n told me I could go they wouldn’t even let me drive my car home last time and I was given a higher dose of meds today I was throwing up in the waiting room waiting for a ride home
