Need opinions please

I went to the ER last night for pressure in my cervix and my back, they couldn’t figure out why I was having pressure but my cervix was inflamed and I had no infection. I went to the obgyn today told him everything and told me not to go to that hospital because the obgyn has no right to be at that hospital just the one that’s 30 minuets away from my town. I talked to the obgyn and all he said “they’re stupid, they don’t know what there doing” he didn’t check me to see if my cervix was still the same or not all he did was a quick ultrasound like always but anyways it makes me feel like the obgyn doesn’t care, I don’t know if I should change obgyns. Any opinions?
