Can CIPD occur with Conduction Block at the Head of the Fibula?

I have had painful burning/tingling that began in June in my right foot/leg and now involves most of my body (including tongue, face, etc) most of the time.  In August, I developed a bilateral footdrop, which was shown by EMG to be peroneal palsies at the fibula head (partial conduction block).  The footdrop improved from August to October, but then relapsed and I developed proximal weakness in both legs and hyporeflexia in the left ankle.  This problem resolved by mid November.  I continue to fall over with eyes closed but can appreciate light touch at all sites.
Relevant laboratory studies (dibetes, liver function, CK, CBC, metabolic panel, ANA, B12, folate, RPR, serum immunofixation, lyme titer, chest film, MRI of brain)have all been negative.
I was recently evaluated at a highly-regarded center for peripheral neurology.  A new EMG confirmed the previus block at the fibula head and also found a (new)"mild ulnar neuropathy at the elbow."  The neurologist concluded that the fibula head & elbow neuropathies were likely due to "habits" (i.e., crossing my knees, etc.), although both I and people who have known me for years believe that I am not a "knee-crosser." The paresthesias were thought to be due to some as yet unknown, but unrelated cause.  I was told that my problem can not be CIPD becuase "the criteria exclude conduction block at the head of the fibula."
It seem highly improbable to me that I would simultaneously develop 2 rare and unrelated peripheral neuropathies.  My questions are (1)does CIPD ever occur with conduction block at the head of the fibula? (2)Do you have any suggestions regarding other possible cause for my problems?
Thank you so very much.
