I think Steel Rat has the right approach. His doctor is performing minimal invasive surgery to correct a very serious injury. I have been there, and I know the pain. In my experience, when pain is either numbing the lower extremities or causing weakness, surgery is a very possible recommendation to prevent permanent nerve damage. Naturally, I am only speaking in general terms, as each case is specific to cause and origin. The older you get, the results of successful surgery are less pronounced. You are still at a good age. If I were in your situation, I would contact this doctor and send him your xrays for evaluation, as a herniated disc may be treated differently than a bulging disc. If he can help you, he would be the man. The trip there, no matter how far, would be the best investment you can make. Having said all that, try simple back message, as all surgeries carry risks. This is currently the best approach to reducing spasms and pain.
Good luck and hang in there.
