CRPS from work injury

Looking for anyone who's CRPS is from a work injury.

Anyone dealing with a worker's compensation company who is not approving recommended nerve block procedure?

My crps is not from a work injury, but I have done stellate ganglion nerve blocks and in my opinion they are hit or miss don't last long and just another maintance for a syndrome with no cure.

Thanks for your reply. Unfortunately I won't know if they work since I am not getting approval for that or anything else.

I know that sometimes any procedure will help to confirm your CRPS especially if they don't work.
