Omg... I just saw your posts about this.
How very scary for you; especially the wait and unknown. I wish you the very best and will keep you in my thoughts and prayers. White light coming at you!!!
Have you considered RSO as part of any type of treatment they offer you?

Often its a sign of fatigue or stress.
Unfortunately, I don't know of any way to reduce the time it takes for the twitch to go away. I get them too and it's so annoying. My last twitch was during my dad's death and lasted over a month. Then one day it was miraculously gone.
Hope yours is...
