I had a bier block when I was initially diagnosed with RSD in March 2007 and had an awful reaction to it!! My doctor injected into the nerves around my ankle bone with a drug called Guanethidine and my body couldn't tolerate it. When I woke up from the procedure, I couldn't co-ordinate my legs at all - everytime I tried to walk, I fell over. This lasted 13 months and I had to go for intense PT before I could walk short distances again. It was only after the block that we found an article on the internet stating that you should NEVER inject into an RSD limb and by that time, it was too late.

I'd speak to your dr and ask him why he is still persisting in the treatments if they aren't helping ... theres no point in going through all of that if you aren't getting any relief. IF your dr is injecting into your RSD limb(s), he should also be aware that you should never do that as it can cause more problems than enough.

Take care and keep us posted!
