Hi iv had crps now for 9months and 2 weeks ago i had my first blocker to my neck, to get rid of the pian in my arm. however the pain in my arms is still there, in fact if anything its still getting worse. my main concern is the pain in my neck form the blocker has not gone yet. i stil feel like im swallowing on one side of my throat and my face and neck feel swollen,with my eye and motuh showing signs of drooping again but this hapens for only half an hour then it s backto normal again. until my face droops again. did anyway else have theses side effects a fortnight after their treatment. how long does it last for? and how long after the treatment did it take for the pain to start relieving? id appreciate any replies im new tothis site and have yet tot meet anyone who has had or still has crps. thanks alot
