For 2 or 3 days I’ve been having severe lower back pain and I don’t know what to do

It hurts to the point I can’t do everyday tasks and it makes me feel like I can hardly breathe and makes me really dizzy. I have passed out due to the pain but didn’t go to the hospital. The pain has been getting worse and worse as time goes on and is on and off pain.

I called an on call doctor and told her all this and she said that it was normal to experience back pain and not of concern to drive to the hospital but I feel like this much pain is not normal.

What do you all think should I go to the ER or should I just deal with it till Monday when I go to my obgyn appointment?
