MRI OF LOWER BACK

  In the last 2 months, I stared having electric shocks in only
  my left leg in front of thigh.  It lasts 1-3 seconds and after that there
  are no residual effects.  I had an MRI of my lumber and here is the result:
  Every thing was normal except:
  " At L4-5, there is a minute left paracentral disk protrusion minimally
  effecting the left venral thecal sac and entrance zone
  to left neural foramen.  There is no significant stenosis or compression
  of neural structures."
  " The L3-4 disc is desiccated and there is minor annular bulging
  with tiny central annular tear.  There is no significant disc herniation,
  stenosis or compression of neural structures."
  Could these cause my symptom?  Are there any precautions that I
  should take?
  Thanks very much for your help.  You are great people.

Thanks for your question.  The alterations described in your MRI scan do
NOT appear to be severe enough to explain your left thigh symptoms.  As a
matter of fact the L4-5 roots do NOT innervate the skin over the thigh region.
Another possibility to consider is a localized compression to the Femoral
Cutaneous Nerve, as it passes underneath the inguinal ligament (the "fold"
between the lower abdomen and the thigh).  Quick weight gains/losses, tight
garments, contusions to that region can sometimes cause such lesions.
I hope this information is helpful.  Best of luck.
