Chronic nerve disease (CIDP) and other nerve problem

[suewatters1]

Hi I am presently experiencing swelling in feet legs and hands.  It’s worse when I am hot. Part of my feet turns red and swells up more when I am wearing shoes, boots or when I wake up in the morning. I also experience the feeling of walking on a bunch of socks.  My hands do turn red also and in my fingers I feel numbness more so when my hands are inflamed.  I also noticed that my legs are more swollen in the morning when I wake up especially when my body and feet are really warm.  I also noticed my nose sometimes goes red.  The difference in temperature when my feet or hands are not swollen to when they are swollen and red is about 15 degrees Fahrenheit.  (I got a digital temperature reader.)
I was researching these symptoms on the internet and came up with Erythromelalgia.  I am going to be 50 yrs old this year.  
But I also have other problems that may be causing this problem.  I have CIDP and I am a diabetic because of the Prednisone I took in 2009 for a relapse I had of the CIDP.  IN 2007 when I had a relapse I first had swelling in my hands which I was told was tendinitis which got really bad but the meds I tried didn’t help.  Five months later I was told I was having a CIDP relapse.  One month later I had 5 days of IVIG.  Ten days before my IVIG I had sudden hearing lost. I had some hearing lost prior to this but I was going deaf.  After my 5 days of IVIG I had 2 weeks of 50 mg of Prednisone for my hearing lost and it seemed to reverse my CIDP and hearing lost to before my Tendinitis symptoms.  Right now I am also experiencing hearing lost in both ears.  There has been a change in my hearing in a space of 4 months at the same time I started having CIDP symptoms.
My nerve testing shows that my nerves in Nov 2012 are worse than they were in 2010 and that my nerves in February 2013 were worse than they were in November 2012.  
So could it be that I have both CIDP and Erythromelalgia causing me problems at the same time?
My Neurologist is also checking me for Vitamin B12 deficiency. My blood sugars are not that bad the worse my A1C ever got was .074 (I live in Canada) and recently it was .069. Some of my CIDP symptoms started last fall and my Erythromelalgia symptoms started this January.

Any ideas would be appreciated.

Thanks Red Star. I found this the Erythromelalgia website.
http://www.erythromelalgia.org/WhatisEM.aspx

The cause of EM is unknown in the vast majority of cases. Peripheral neuropathies underlie many, and in some cases EM may be secondary to other disorders like the blood disease polycythemia.
I have a Neuropathy disease called CIDP.  I was wondering if I could be having problem with both.  A relapse of the CIDP and a new problem which I think is Erythromelalgia. or just the Erythromelalgia causing symptoms of CIDP.

"Erythromelalgia is most commonly seen in the secondary form. This may usually occurs in conjunction with myeloproliferative disorders. Along with the myeloproliferative disorder other hematological abnormalities such as polycythemia and thrombocytosis are often seen.

Studies have reported erythromelalgia to occur in from 3 to 65% of patients with myeloproliferative disorders. A comprehensive listing of causes of secondary erythromelalgia would include: polycythemia vera, essential thrombocythemia, myelofibrosis and chronic myelogenous leukemia. Some reports have also ascribed this condition to being related to rheumatoid arthritis, gout, vasculitis, pernicious anemia, SLE and possibly drug induced (bromocriptine, nicardipine, nifedipine, pergolide and verapamil)."

Excerpt from the article Erythromelalgia by Stephen M. Pribut, DPM

Check your vitamin B12 levels personally.  Japan and Europe have risen the B12 serum range to a minimum of 500 or 550pg/mL (not optimal for good health however) but most countries have appalling low reference ranges.
