Thanks for all the input. I've already called the hospital to tell them I'm not doing another bier block.

I'm still going tomorrow. When I went there to do the first two blocks, the nurse talked to me about "other options", and mainly mentioned a nerve block which would help my blood vessels open up. So I suppose she was reffering to the lumbar sympathetic blocks.

I've spend the last days reading up on CRPS. And I'm now reading as much as I can about nerve blocks. I'm gonna make sure I can see the doctor who's in charge of following me up, and talk to her about it!

I'm also considering changing hospitals. But there's only one hospital in Belgium which may be a better choice, and they also recommend contrast baths as part of the physical revalidation on their website.

The first treatment they recommend is what I'm having now too. Injections with miacalcic (calcitonin salmon) and physical therapy. If that doesn't work, their second means of treatment is an IV drip with bisphospanates...

From what I've read the best treatment I can get right now, and as soon as possible is the SLB's...
