The reason the leg “goes to sleep” (becomes paresthetic) can be due to spinal or non-spinal conditions. If there is a compression present in the canal (a disc herniation or spur), the injection might make some sense. If there is no spinal pathology, there would be no indication for this injection. By the way-you note no pain but only paresthesias (pins and needles). Injections are less effective if no pain is present.
