John,

I suffered for a few years from a slipped disc which stopped my running days! However, I finally decided to see a physiotherapist and she has worked wonders on my back. The problem is that scar tissue builds up around the injury and this is weak stuff that is prone to go at any time. The longer you put off seeing the physio, the more scar tissue builds up. the physio will break down the scar tissue and replace this with healthy muscle tissue that should ensure your back stays in place. By all means take the various supplements but DO see a physio asap - I'm glad I did!
