In Reply to: PN or not PN...that is the question. posted by Alan on March 18, 1998 at 18:43:21:
      What other types of diseases, conditions or diagnosis mimic some of the
  major symptoms of Peripheral Neuropathy?
      I have on/off burning down the sides of both legs to the ankels.  There is numbness
  in these strips down my legs, along with skin sensitity that comes/goes in
  calves/thighs.  After 3 EMG's and MRI, no nerve damage can be found.  I believe
  something called Ischemia (lack of blood flow) is one disease that mimics (and
  be mistaken for) PN or nerve problems.  Entrapment by Trigger Points of blood
  vessels/nerves is another.
  Help!  What else can I do or where can I go to start getting a diagnosis?
  What kind of Doctor (other than the Neuro's I've seen) should I go to?  Thanks
  so much!!

Thanks for the question Alan and sorry about the delay. Peripheral neuropathy is a disorder of the peripheral nerve (after it has left the spinal cord) and damage to it can cause problems with weakness, numbness, or burning. The EMG test that you mention is very sensative at picking up abnormalities but no test is 100% sensitive. Abnormalities of the central nervous system (brain or spinal cord) can also cause sensory changes in limbs. Many patients present with these types of symptoms which if not diagnosable initially will clarify themselves at some point so follow up is important. Vascular abnormalities can somestimes also cause these symptoms. You investigate a vascular medicine specialist to rule this out as a cause. I assume the MRI you had was of the lumbar spine? It is also important to have a good neurologic exam which can help identify any objective evidence for a suspected abnormality. Good luck.
