Yes I get this sometimes, a few days ago I had the burning sensations and soreness suddenly in my middle and upper back. I was pretty worried, but this is the third day, and it's definitely subsiding. Phew. Lol, I seem to have worse CRPS symptoms around that time of the month....but this was a new one.

It's natural to panic with this, but not everything is a dramatic turn for the worse wish I could remember that, but it gets me every time!

Bram.
