I had an even more minor ruptured disc 18 months ago. Went to the specialist, had the MRIs, etc. The specialist was mad keen on surgery and epidural injections; I wasn't keen on either, tbh.
Thing is, as far as I can make out, most of the pain and discomfort I had was from the muscles seizing up around the disc, from being tense most of hte time. The solution was lots of back exercises, things like the plank to build up abdominal strength and so on.
But I was on the bike again within a few weeks, and ran the marathon a year later, and now only really have discomfort if I haven't stretched my back for a few days.
I've spoken to a couple of people I know since then about their disc injuries, and it sounds like there really are levels of injury there; obviously I was lucky! Fingers crossed for you; it sounds like the bad ones leave you bedridden for weeks.
