Today I am going in for a Lumbar Epidural Injection. Several years ago I slipped a disk and about a year ago I started getting pain in my lower back and into my legs. After months of physical therapy which did not help, the docs decided to look into it further by running more tests and MRIs. After doing so they found that the disk between L4 and L5 not only slipped but also the bone L4 has also slipped. The docs gave me 3 choices, 1-much more aggressive physical therapy, 2-Lumbar Epidural Injection or 3-Surgery to repair the slipped disk and bone.
I chose options 1 and 2 as well as loosing some weight as to take some weight off thee ol back. So today is the day I get thee ol spinal injection

and the aggressive physical therapy starts next week. I already changed my eating habits and have lost 10lbs in 3 weeks. Big life change ahead for me
It doesn't sound like you have to worry about the weight issues but if I were you and if you do have options 1 and 2 as I did, I would highly recommend going that route over getting cut into.
Good Luck with what you decide and if you are interested in my progress please feel free to hit me up on ICQ.
