pins, needles, burning and cold skin sensations

I sound like many who are seeking a cure or a diagnosis for an uncomfortable skin sensation.  I have skin that is burning in many places and pin and needle sensations throughout my body, primarly on the arms, back, chest and intermitent of the legs.  At times, my skin, arms and legs, have a feeling like a cold damp breeze feeling.

I have had multiple MRI's to the neck and spine, various blood test and visits to rheumatoligists.  I am running out of doctors to visit and need some help.......  This is the most uncomfortable feeling to deal with day and night!!!!!!!!!!  

I have experienced temperature sensitivity.  I have tried neuroton - with no success.  Any direction that I could try next?
