Thank you all for the replys I think it must be as you say the chronic just means long term.
I have now been officially dx with this crps although it has been mentioned several times.
It was pain management that made the dx and prognosis is it can't be cured just help trying to control pain.
It takes a bit to get your head around this as to why it can't be cured,I have nerve damage small fiber through this.

Thanks all
