In pain

I’m in pain and have no idea if it’s from the uti I had and it got worse or what. My side hurts so bad. I called the doctors office and the assistant said I have to wait until my appointment well I can’t wait cause it hurts and I’m scared it’s a kidney infection. I don’t want to go to an emergency room when I can see a doctor cause the emergency rooms don’t give a shit about you unless it’s something traumatic
