Covert intraforaminal block using high and low concentrations of lidocaine, and similar covert spinal (intrathecal) block, consistently suppressed phantom limb pain (PLP) and nonpainful phantom limb sensation (npPLS). Control procedures (sham, saline, contrast injections) did not. Group sizes were as follows: spinal block (n = 11); intraforaminal block with 1% to 2% lidocaine (n = 13); controls (n = 13); dilute intraforaminal lidocaine (n = 15).
