I remembered a few more things that probably contributed to the improvement of my symptoms.
1. Using an inversion table, slowly increasing the angle as tolerated, while using a rolled-up hand towel under the neck to assist with maintaining correct curvature. Un-weighting the compressed disc was a revalation for me! Slowly, once inverted and unweighted, moving the head and neck around to free up the compressed, stagnated disc, to increase circulation and decompression. If you happen to be in the tacoma/Seattle area, or have someone out this way, you are welcome to have my table. I haven't used it in quite a while. We got it off of Craigslist, so it isn't immaculate, but if you have anyone passing through our area, it's yours. =)
2. Hydration. Discs contain a lot of water and need it to maintain their correct form.
3. Chiropractic adjustments. Not all chiropractors are created equally, and this didn't lead to sudden relief, but because my symptoms have improved, and chiropractic adjustments were part of what I tried, I mention them.
The doctor who administered the steroid injections was an osteopath; Jason Attaman, of Seattle.
I think the best way to go will be to hydrate, decompress, gradually increase decompressed movement, and reduce stress.
Best of luck, Paul!
