Is the Plasma protocol of Dr. Swank still used and what possible has replaced it?
When I thought I was having another relapse the first time I was on steroids, my doctor was ready to order a plasma exchange. I think that's all they had before steroids and may still be considered an alternative if they ate not helping.
I never had it, because that terrible feeling was caused by the steroids themselves.
So there must be some doctors who do it, but it must be expensive and have its own risks.
