Hit the proverbial wall....

Sorry to read Doug, from what I know "back problems" can be any number(thousands) of things so a proper diagnosis isnt as easily made. You would think with technology today it would make it easier for the docs. But writing a script for pain killers is easier for some of them. Stay positive and as 5.7 Hemi mentioned try shedding some weight? Weight loss will help both physically and mentally.
Be well
