BlueAtlas, thanks a lot for your advice.
I still didn't hear what my doctor has to say, and, due to reasons of where I live (and our healthcare system), I probably won't be able to know anything until at least two weeks have passed.
The pain I described in point 2) (joint of neck and spine, and below) has gone away, but I get strong sensations of "pulling".
It's as if all the muscles around that area are stiff and contracting.
It's not really paining but really irritating.
I can't keep my neck in a way for too long and it starts "pulling".
I can't even lie down on my back without getting that feeling... it's as if my neck is shrinking into the shoulders...
Is this something bad? I tried to search a bit but didn't find anything related to the "pulling" feeling.
And it's really making me nervous.
I'd really appreciate any advice or at least a temporary remedy or precautions until I get to the doctor.
I don't know where else to ask and honestly I'm feeling really really bad with all this.
thanks
