Babsinpain,
18 mos. ago, you say you were "successfully treated".
What's that mean? Exactly? You were "cured", then, it happened again?
How soon, how long were you cured for? (Two questions).

This is a very complicated issue, and, I simply cannot get into the "Welcome aboard" type posts.
If I am to be of help.
I need to know some facts.
Please, give them?
(Yes, You ARE at the right place, but, we need facts)!

How long after you were "Altogether cured", did the second incident, and onset (again two questions), happen? I'm not "drilling" you, but you'd better be prepared to answer this to your doctor!

I'd bet, that you Never were "cured" the first time.
The second injury just brought it to the fore, again.

If that can make sense for you.

Please, believe me,
I know what a second injury can do.
Nobody can choose their "victim"...

And, that's why us with rsd, must be so careful.

Please, give us more details?

I'd love to help!

PM me, if you wish.....
