For almost 2 weeks now I'm been having pains in the back of my neck and my upper back.

My neck (and sometimes other parts of my body) have been twitching a lot.

I get really nauseous and my head also feels weird, almost like a dizzy sort of feeling when im standing.

As of writing this post, I have yet to visit a doctor about this

I was wondering if this has happened to anyone and what they did, or what I should do because I don't really know how serious I should be taking this and I'm freaking out about it.
