Symptoms progressing

Initially My friend had symptoms of her CM mainly on her left side. (Shoulder and forearm.) Is it common for symptoms to migrate through other parts of the body? IE: the right side. Does that mean her condition is getting worse? Im secretly worried.

It's all very moveable in the head. So, it could mean she's getting more compressed, but it most likely means she's the same but pressure is off in one spot and on in another being pressed. I'm new to this, but if it gets any worse, maybe suggest she call her doc to run it by . It's very nice of you to be concerned.

Every persons Chiari is different and progresses differently. This could be a sign of progression for sure. To me, new symptoms mean progression.
