Hey there!
I was 23 when I was dx w/CRPS and after having tried EVERYTHING under the sun (much like you have), I am now 25 and on my way to my SCS trial very shortly (w/in the next couple weeks). I can't live with this pain the rest of my life, and as much as I resisted it, I've gotta give SCS a chance. There is no "right" age to suffer! Although you'd think some docs think I should, given their reaction to me- but that's a cross many of us w/CRPS must bear (bare?) lol, anyway, w/a condition that sounds very similar to mine, I'd say go for it. Good luck, and God Bless!
