Thanks chaps
Happily, that horrific wrist pain has gone for now, and I'm just (ha, 'just') left with the cold, aching burn of the steady CRPS pain throughout my arm. It's nasty enough by itself, but I'm much much happier now my wrist feels a bit better...
One interesting thing I've noticed since its got colder here, and my arm pain is much more constant, is that there is a definite line where the symptoms end - right in the middle of my traps (the muscle between your shoulder and neck). It's really strange. I think it's the most obvious CRPS edge I've got!
Hope everyone out there is doing ok tonight.
Bram.
