I totally forgot, but the other thing I brought up at my most recent appointment (with the doc who did the block) was the possibility of IVIG. They said they don't do it, but that other doctors or institutions may. It's just one more thing in a long list that I'm all for trying before having strange devices implanted in me. By all accounts it's something that there has been good success with for CRPS patients, although I'm not sure it's actually approved for us. But, it is something I want to explore for sure. Just one more thing I'm doing for myself (or trying to), that doctors aren't.
