The British Medical Journal (BMJ) put out a publication that investigates the effectiveness of different treatments for Lumbar herniated disc injuries, based upon the current research.  The authors then catagorize the treatments as “likely to be effective”, “likely to be ineffective”, ”unknown effectiveness”, etc.  I makes for interesting reading because one of the most prescibed treatments, over-the-counter NSAIDs, is found ”unlikely to be beneficial”  according to the research uncovered by the authors.  Check out the other findings by this group by following the link to the article titled,
