Hello and welcome aboard. Hope you are having a less pain day today.
For me, I was told that the block will not help me. 10 years Crps2. However, there are others that this has worked, is still working.
With that being said, I am happy to hear of second opinions and extra doctors evaluations; sounds like you've got a great medical support....
Please with whatever decision you make, keep us updated. Successful or just venting.
Keep up the fight.
