Hi,
I really was going to post the same question you did about the RSD spreading.
I also have RSD in my left ankle and lower leg but recently started having full body spasms and twitching and discoloration in my hands and tremors in my legs to the point where I feel like they wont hold me up sometimes.I then stated to experience burning pain that would jump around all over my body, even in my face along with my eye twitching.I am also wondering why that is?The Docs cant give me an answerfor the burning all over but put me on Baclofen for the spasms.I just started it so cant comment on its effectiveness.
I was also wondering if anyone experienced their pain coming in cycles.For example I consistently have 4 good days where I can sleep and my pain is very mild and then 4 days after where all my symptoms are flared up.Has anyone experienced anything similar?

Thanks
Renee
