Hi and welcome! I wish I knew what was permanent and what isn't. The pains I know are permanent, though I don't hurt every day. But I'm not sure about lead legs. I lived practically lead-leg-free for two years after a 6 mo course of solumedrol, now its back with a vengeance! Both legs and arms too.

The standard rule of thumb for a relapse is unrelenting symtems lasting three days or more. If it keeps up you may need a trip to the neuro, and some steriods.

Good luck, and hope your dx is soon.
