Smoke,
I've had rsd since 83. It's a horrific condition, and worse, it has a big possibility of spreading.
Be sure you have a good neurologist, possibly a PM psychiatrist, and get exercise!
RSD, is "Use it or lose it".

Have your visited rsdsa.org?

there are other good sites, listed at the top of the page.

Also, when someone tells you, that you're not strong? You're not talking to a "friend". You are talking to a Non Compassionate Zero.
This disease will "Mark" your friends and non friends for you.

Learn all you can, from this site, and any others.

You can get a gel to apply locally that has such goodies as lidocaine, baclofen, and others.
(I don't use it, as my rsd has gone full body), but, many folks do) Someone will help with that.

All the best,

Pete
