Please don't be upset.
The shot masks the pain by deadening the nerves, but the mechanical cause of the pain (bulge and herniation) remain.
60% of bulges and herniations are directed posteriorly. They can be pushed back into place with some variation of spinal extension. (standing back bends, yoga "cobra", etc.)
40% are directed laterally or anteriorly. They will be pushed back into place with pelvic side glides combined with some amount of extension, or with flexion (like bending forward).
Once you figure out which direction you need to move the spinal segments above and below the herniations/bulges to correct them, then you keep doing that corrective motion every couple hours until you've been pain free for a week.
The spine is self correcting. We only go with corrective motions to help it do what it wanted to do all along. (a little more "oomph" as it were)
Hit up your library for "Treat Your Own Back" by Robin McKenzie, or find a certified or diplomate MDT physical therapist in your area.
I've treated patients who've had chronic pain for 20 years, yet they only needed 6 visits to learn how to fix themselves so they can finish healing. It's never too late to fix yourself. The PT is only there to teach you how. You are the power!
