question: I would like to know in layman's term what the following means:  L3-L4; left lateral disc bulge causing nueral foraminal narrowing. Central disc protrusion is identified.  Some of the disc material is seen to extend to the posterior superior aspect of L4.L4-L5: Central disc protrusion involving the left lateral recess.  There is ligamentum flavum hypertrophy and fact hypertrophy.L5-S1:  Facet hypertrophyI have been having lower back pain since October of 2009 which radiates down my right leg...on the outside of my leg.  I have been seeing a chiropractor who has told me that I have some serious issues going on but it is possible to get this under control.  I also have RA.  I am taking anti-inflammatory meds twice a day, Methotrexate weekly and Enbrel injection weekly.  But this back thing is not getting any better.  I work on a computer all day so I sit for 8 hours.  The pain has really changed my life...it seems to be constant now and hinders me from doing things I would enjoy.  I was wondering if I should see a specialist and perhaps consider a nerve block.
