My wife's doctor has suggested that she should receive Sympathetic Nerve Blocks. My wife's concern is she doesn't like invasive procedures and above all feels strongly that Sympathetic Nerve Blocks after 8 years with RSD is asking for trouble. Both her and I have read somewhere Sympathetic Nerve Blocks are most effective in the beginning stage of RSD not years later. Can anyone elaborate on this or can point to literature that states this, or other wise?

Thanks
