My 2 cents:
At age 35 I herniated the L5-S1 disk-the most common. It hurt like a M-F--and was initially diagnosed wrong by a complete incompetent. Yeah, sciatica etc. They wanted to do surgery but I stayed away and found a good, traditional chiropractor--hand manipuplation, not that gadget that they push and click. He was also a pragmatist--going for what worked, not for what was SUPPOSED to work.
He gave me a lot of relief. I also did research and found that the surgery was not likely to give me much relief--"60-90% of patients are ambulatory after surgery" Ambulatory? that means walking around, right? I was walking around already.
I also found that after 4 years of surgical vs non-surgical treatment most patients were about the same.
So: ICE your spine. Get those blue ACE ice packs and do it 2-3 times a day. At first it will be awful and clammy, but when you get used to it, it will give you relief.
Next, try to keep your back straighter. If you must sit in a desk chair, try to get one with a waterfall seat. For other chairs, they make triangular pillows you sit on that angle you--especially good for cars. Also, it helps to pull the seat up more than usual, but angle the back more, bending your knees more. At night, a firmer mattress, a thinner pillow, and sometimes a pillow under your knees helps.
Exercises.
The last time I reinjured it, my Ortho gave me AWESOME exercises. Basically, a lot of SLOW situps, you pull up halfway and hold for 10 seconds and let down. Reverse situps (on your stomach), again slow.
Leg stretches. On your back, pull one leg up with the knee bent to about 90 deg, then push it to the opposite side (so if it's the right, push it to the left), back and slowly let it down. You'll FEEL the vertibrae releasing! In 2 weeks I had TOTAL relief--I was amazed! But this guy knows his shit when it comes to re-hab exercises!
The latest surgery (after simple disc removal) is disc replacement rather than fusion. Disc replacement is far less invasive (4 hrs of surgery vs 6 or more), they only go in through the front (as opposed to front AND back) and they don't need to take a bone graft from your hip (a third incision). Fusion FREEZES the spine, replacement retains or RESTORES mobility. There are only a couple of products on the market yet, and a couple are in clinical trials. Unlike other joints (hips, knees) disc replacement is designed for a lifetime, not the usual 15 years.
Good luck!
