Hi Dana,
So very sorry to hear about your diagnosis, would you like to tell us what they've said so far? We have several people here with a recent RSD diagnosis, so you're in good company.
I know we'll be happy to answer any questions if we can - I'm sure you're full of them, of course. I'd never heard of RSD/CRPS till I got it...I have it in my left wrist and hand, it came on after I broke my arm in a stupid fall - just slipped on wet greenery, chasing the dog home after a typhoon....kerbam!
Where is it affecting you and how did it begin? Perhaps some others can help too - but in the meantime my best advice would be to read through the back forum pages - there's not much we haven't discussed on here

Also, look at the links sticky post, it has numerous URLs for sites to help you learn more about it.
Don't get too depressed, you might be one of the lucky ones - sometimes if you get an early diagnosis and start treatment right away it can be halted.
Take care, good to see you here anyway,
all the best!
