Pain in Neck

K
I'm 10 weeks with a terrible pain in my neck that hasn't gone away for 4-5 days and hasn't really been getting better (and for what it's worth to the left of my tailbone is achy as well sometimes). 
I'm getting my first trimester ultrasound on Wednesday from a clinic - and after that will be able to get a regular doctor. 
Anyone else have it? The pain starts almost in the middle of my neck! I almost wonder if it's because my wisdom teeth started coming in RIGHT as I found out I was pregnant 🙄!
