Have you checked your pain vs. a nerve ennervation pathway chart? It's easy to say that you have impingement at level x so that's your pain generator but, in a rather public talk given around a decade ago, Zeegers pointed out that it isn't always simple. He had a patient with two disk, one obviously bulging and a second slightly so. The main pain generator was disk nucleus leaking from the slightly damaged, but non-obviously torn disk, not the bulging one. I wouldn't expect that your diagnosis would change if you checked but it's easy enough to find an ennervation pathway chart on the internet and make sure the part of your body that is feeling pain is linked to the nerves that are being pressed at L45.
