FWIW I have both a standing desk and sciatica due to a bulging disc injury. My physician, chiropractor and physical therapist all agree that I should stand and walk as much as possible (all day at work is fine) because of the benefits for my back. Mainly, they claim that I will spend a lot of time making small movements -- shifting weight from side to side, repositioning myself, etc. -- and these movements of my spine are beneficial. Evidently, these kinds of movements (and also a lot of walking) move the fluids and nutrients in the spinal cord that keep the intervertebral discs vital.
