Pain in left side of neck, shoulder blade and arm?
I'm 34 weeks pregnant(not sure if that's important) and some days, alot recently I have this achy feeling in the back of my neck and shoulder blade and my arm it feels similar to sore muscle pain and sometimes it feels like it's in the left side of my chest. I don't do any heavy lifting or excercise that would pull something, could it maybe be how I sleep? I put two thick pillows under my head at night and I sleep on my left side sometimes with my arm above my head. Thanks for any info.
