My advice would be not to get your hopes up til it's a more definite "Yes we're going to consider this properly". I had 4 doctors suggest it to my pain clinic who have said maybe, maybe, maybe, oh wait, no. They say it is not successful on more than a small area/one limb max (and doesn't work on back pain at all but that's not relevant to you). I don't agree, but at the end of the day he's the doctor and gets final say over my body. Another thing to consider is that if I'm wrong and he's right, what happens if the CRPS spreads to other limbs? My argument would be that having one limb less to worry about would be a miracle. But again, we don't get that final say, they do. Not a pleasant feeling when there's no hope of any future treatment other than counselling.
