Your question was “anyone have good success”. Yes. I have a L4-L5 diffuse bulge. What helped me was a machine called DRX. (Decompression/traction to a specific area). Manual manipulation helped a bit but after 3 months I still had significant pain and my chiro suggested the DRX machine. 1 week into it and I was 90% pain free. Took another 2 months to get that last 10% but so far so good. Back to swimming, biking and core work. Hope to be running very soon. Check it out and see if it is an option for your issue.
