hi all, has anyone had experience with pain blockers?

i just started a series of these shots and i'm wondering what to expect, i was told that there is an 80% chance that the RSD will go away and i just don't want to get my hopes up again. the doctor has finally diagnosed me with thorasic outlet and rsd and has put me on fentanyl patches, will the combination of the blockers and the patches help with the thorasic outlet as well?

 

any guidance would be great!
