I am SO sorry you are dealing with this! You have INDEED come to a wonderful place tho! Both the PN and RSD forums here are very active full of fantastic/knowledgable people.

You have asked a VERY valid question because I've seen it time and time again Drs passing it off as one in the same....

I personally have the constant 'burning' nerve damage PN type of pain in both legs.
What you describe certainly sounds like RSD!
But I encourage you to check out BOTH forums here because you've also brought up another VERY valid point Re: Lyrica!
As a matter of fact, there is a very active discussion on the PN forum about Lyrica. You need to see this!

Let me know if you have difficulty finding these two forums here at NT and I will provide the direct links for you.
Go to the main menu and scroll down....you'll see them.

You need to get some answers ASAP!

I'm active on both those forums, so I'll be seeing you there!

Hang in there! Help is on the way .....
