Welcome Kermit,
I'm with Jo*Mar. Always good to have a thorough workup. At one point early in my journey I had nerve compression from swelling and that alone caused all kinds of bizarre twitching that went away when the swelling resolved. CRPS is a diagnosis of exclusion so they really need to be certain there is nothing to treat that is contributing.
I am so sorry you had to come and find us but you will find good support and community here. Come see us when you have questions, need to vent or to share good and bad news.
Sending Healing Love,
Littlepaw
