I've had two bier blocks now, and I'm sheduled for another one next friday. Both times they've injected medications into my foot, where I have the CRPS.

Can anyone give their opinions on the safety of this? I'm reading but I can't find much info on it. But some sources tell me it isn't safe to inject a needle into a CRPS area. And that it can make things worse and cause spreads. I've also read that just a needle can cause CRPS in the first place...
