Should I make the er trip?

I woke up about 2:30 am, burning up and could barely move. I took my temperature and it was 100.1. It’s now 4 and my temperature has went down to 99.9 so not much. I’m having this lower back pain and it’s pretty consistent, my legs/hips are killing me when I try to move. I’m 38+4. I’m just worried, and wondering if I should go in to the er?.
