Amy,

Sorry to hear that you are not getting much relief from the blocks.

I did not respond at all to sympathetic lumbar blocks for my foot either.

As mentioned, what is your plan moving forward, and who is "guiding" you as your primary CRPS doctor? I think it is important to have a primary doctor who leads the way if you will, through options. But along with that primary doctor, you need other professionals involved in your care. That may include a physical therapist, massage therapist, neurologist, pain management doctor, etc. Best to take a "multi-disciplinary" approach to CRPS. Studies have shown that people that apply this strategy have better results than treating with a single doctor.
