No, I have not tried it. The new pain mgmt doctor I saw mentioned it as an option but said the side-effects were more problematic than other opioids. We decided to try the patch to bypass my GI problems. It ended up being the best choice for me and has worked out well. This is very new (only second month on the patch) so we are still working on finding the right dose/strength.

I also receive IVIG monthly and although it doesn't make a huge impact on my permanently damaged nerves, it does help some. I know this because after 3 weeks, my nerve pain is much worse when the IVIG wears off (half life of only 21 days).
