Is this normal?

I went to the er the other and found out I have bacterial vaginosis and a bladder infection. My temperature keeps spiking to 102 or going down to 96. Which happened to me the last time I had a bladder infection..however my kidneys hurt so bad I can't lay on my back and it hurts to walk at times. I see my obgyn on monday but i was just wondering Is this a common thing with having both infections at the same time?
