Hello and welcome,
Sorry you have the extra worry about the discs. I presume you have had an MRI which will give the neurosurgeon some idea what is pressing on what and whether he will be able to do something to help you.
As carouse said, if there is no cord or nerve compression then often times I believe it is best to leave well alone but if there is some compression then he maybe able to help reduce the pain you don't need to have as well as RSD/CRPS.
My sister had herniated discs between L3-4-5 and was virtually crippled by the intense pain she had, she saw a neurosurgeon who did a disectomy and she has been perfect (back to golf) since.
I realise that her not having RSD has made her recovery much easier, I would hope your neurosurgeon (if you need surgery) will refer you to an anaesthetist who knows about RSD and will know what type of pain relief and anaesthetic you need so as to lessen the chance of a flare.
Heaps of luck
Tayla
