Although surgery is a last resort treatment, if you've had a decompression, then you probably needed it.
Epidurals on the other hand can be very fickle, in that they need to hit the exact spot for any lasting benefit, but near enough will help briefly. [sm=scratchchin.gif]
I hope you've been given stretches to do, but not extention (stretching backwards) exercises, if you get pain locally in your low back. This is because bending backwards is likely to irritate the very joints that are causing the local pain. There are differences of opinion & I have talked about this in other threads, so do have a rumage. If you look thru the threads on back pain or click on my profile & click any of my older postings that look relevent. [:-]
I was treating someone once on the NHS & her company that paid for private health, sent her to see a medical doctor for an epidural. After having this she reported back, saying that she was the only one in the waiting room for an epidural, that was there for the first time. When inside she told the doctor that she was having osteopathic treament from myself, to which he replied - well people can be seeing an osteopath for life & it still doesn't fix the problem. A bit unprofessional we thought & misinformed. Also, ironic when he had a waiting room of folk needing repeat procedures at a far greater cost & that actually doesn't address the underlying problem. Or is that me being unprofessional? [&:]
Some osteopaths use acupuncture as well, as a pre-treatment, then use an osteopathic approach. This is ususally western/ medical acupuncture, I do myself, but have great respect for Traditional Chinese Medical & 5 Element acupuncturists. I wish I had the time to study these, maybe one day. But they are alternatives that you may want to consider.
Here's a direct link on the various acupuncture approaches, so you don't have to fish about on site - http://fp.osteopath.plus.com/holistic-centre//serv/acu1.htm
Good luck whatever you decide - Andrew.
