Can an arm impingement be a catalyst in an Arnold Chiari tramua. I did not know I had this until I experienced an explosion of pain in my arm and later found out that I had this Malformation but at the same time I had an shoulder impingment?
I also have ACM. Based on my memory of comments from my neurologist, I would say that an arm problem cannot cause ACM. I gathered that ACM was a condition from birth, but may not present symptoms for years (or never). You can't "cause" ACM. In my case, I was talking about a childhood diving-into-kiddypool incident.
