My question about neck trauma was referring to the strangulation event.

You exhibit classic PTSD symptoms. All of your symptoms can be due to PTSD. Even the dystonia can be triggered by PTSD.

Why do you think you had a concussion, too?

As one who has experienced PTSD from 2 separate traumas, I have a good understanding of how symptoms can manifest but appear to not be related to the traumatic event.

Have you had any post trauma counseling/therapy? You need it. It is important. You should have been offered it immediately after the event. Did you file a criminal complaint against the strangler?
