I have disc hernation @ t7-t8 with flattening of the left ventricle spinal cord, disc protrusions and spondylolisthesis from L4-S1 resulting in bi lateral stenosis but more on left. Paresthesias on left leg and tingling in hot weather why NORMAL EMG?

The EMG/NCS. test is a very unreliable (and UNCOMFORTABLE) diagnostic test in the diagnosis of lower extremity symptoms due to spinal cord/disc abnormalities. It can be normal when imaging shows herniated discs!! Hope this is helpful Dr Z.
