I would see a neurologist before getting anymore nerveblocks. You can always go back to the pain management dr for more nerveblocks if the neurologist okays it. I had nerveblocks from a pm dr before seeing a neurologist and wish I saw the neurologist first. She prescribed a more effective and less invasive way to help get me to get some movement in my hand and fingers with prednisone and lessen swelling of rsd a little. It helped alot more then the eight nerve blocks I had prior. They didn't do much at all for me except cost me more money and discomfort. Everyone's different, but this is what happened to me. I hope you find someone who can help you feel better soon.
