Hi Rachel,
Welcome to the forum, although I'm sorry you've had to come here and this has happened to you. As you've probably read above, my situation is very similar to yours.
I recently did a post about how my RSD started, what happened with the blood test etc, on my blog- as Nov 3rd marked the 9 year anniversary of it all starting. Instead of me writing it all out again, you can
click here to read what I wrote. Once you're on that page, you can click on the "Home" button under my title picture to get to the normal blog page with the most recent posts, or click on the "RSD/CRPS stuff" link in the "blogging categories" section on the right side of the blog to read my other RSD posts.
If you have any questions about my story, just yell out.
Oh, and just quickly- I can never have blood taken out of my right arm again. They used my left arm for a long time (although I had emla cream- a numbing cream they use with kids when they need blood tests put on before the blood draw as it helps numb the area) but now those veins have packed it in so I mostly have blood taken from my foot now, using a kids size iv needle.
