Hi Jamie,
Sorry you've been going through such a tough time for so many years, must wear you out... Just my opinion, but your doc doesn't sound like he's doing his job properly, the most basic rule of CRPS is to treat the pain appropriately - and of he doesn't want to give you pain meds or discuss your hospital anaesthesia options then he is being downright mean. It is so important after all your problems and spread, that they give you decent pre-op pain treatment, and extremely good post op care, including whatever you need when you go home. I would be very wary of going on for the op without knowing how they are planning to deal with your pain. This stuff is just way too important...
I wish you all the luck in the world, and good for you on coming down on the pump relief to this stage. That's one long hard road!
Hope your op goes well and you get some answers and reassurance before you go in.
Bram.
