Barb,
I'm glad I could help, and CONGRATS on the treatments!

As for the change in symptoms - I've had RSD for 8 years now, and have very few of the same symptoms now that I had when it started - it seems that the disease just tends to change (not evolve, really) over time.

I started with burning pain in the back of my right knee - now, my symptoms change on a daily basis! Burning, tingling, aches, sharp pains, front of the knee, back of the knee, feet, left leg......sometimes all, sometimes only one or two!

I know that's not necessarily helpful, but I would say that it's definitely important to keep your doctor updated on your symptoms - if things are progressing/changing, the doc needs to be aware so that your treatment can be modified if necessary.
