I am very sorry to hear of this. I am sure that was very scary and painful. And to make matters worse you were ignored by medical personel. Unfortunately no one here can diagnose you, I am sure you are aware of that. It could be so many many things!!! Just try to keep at those doctors!! Tell them your symptoms and when they occurr and for how long. Ask what they think it might be and what testing they might recommend.
Being paralyzed during a dream is actually totally normal. We are all paralyzed during our REM sleep, it keeps us from moving durning sleep so that we stay asleep. If you wake up still paralyzed, then that is another thing and you need to tell your doctor.
I am not thinking that anything you have said here really lights up the MS alarm. That is good news. Some MSers have a syndrome called L'hermittes ( I might have spelled that wrong). Anyway that is when you put your chin to your chest you get an electric buzz or shock. It is very very specific to that movement though and I have never heard of it in the brain or head. It is generally not painful or long-lasting and it goes right away when the head is back upright.
Good luck on your quest to find answers.
