It's not time to get depressed yet! but yes it does sound like you have a mild grade I disc injury. You make no mention of leg pain.
What you do have is the crossed sign - raising the left leg hurts in the right low back, not in the right leg luckily.
That is both good and bad news. The good first. A postero medial disc herniation -
mild in your case, since there is no leg pain, not really a true herniation (yet) - typically gives the crossed sign.
The good news is that PM bulges usually respond quicker than PL bulges to chiropractic manipulation. But even though the pain subsides quicker than PL, IT STILL TAKES SIX WEEKS TO HEAL.
The bad news? More PM disc herniations end up in surgery with all the complications. My theory, is that PMs get better quickly, and folk very quickly forget they've had an injury, start sitting, bending, gymming, stop the exercises too soon, thinking it was no big deal. Every disc injury is a big deal, as you know, and you never know in advance whether this is one that's going to end up in surgery.
These slipped disc rules
are for bad cases, and I don't think you need to take them literally. But I would follow the spirit of them. Bend less, sit less, do your exercises faithfully, be careful. And go on doing them FOR THE REST OF YOUR LIFE every morning before getting out of bed.
Plan to get properly better
otherwise it just comes back next week.
There is a place for Massaging bed rest
but I doubt you need that at this stage. But if in a couple weeks the slump test is still positive then take a week of this modified bed rest. Go from Lower back pain - disc problems or glutes? to other Chiropractic Conditions often treated…
I hope this has contributed.
