As everyone said, see a good doc ASAP. Been battling back issues for decades and putting off multiple fusions. Not sure how old you are, but these are common "aging issues" for many folks or the results of injuries (or both). DDD is a mystery to the medical community. Personally, I went back on the wagon with diet and supplements and so far things have improved to the point where I can put off fusion again (LAST RESORT IMO). Hit CL and buy an inversion table as that helps with decompressing the discs.
