Woke up one morning (week & 1/2 ago) had numbness in finger tips Right hand thumb, forefinger, & middle.  I think i had my should pushed up under my head and arm twisted... This went on for one week then started shooting pain in arm & hand, back of hand is now numb as well. 

Monday MRI revealed herniated disk. Dr wants MRI with contrast (tomorrow morning) of full skeletal & brain. The Neuro PA told me that they saw an "anamoly" on spinal cord below the ruptured disk but did not want to speculate before further MRI.  What should i make of this?  

They have scheduled me for a block in one week. Question, should i expect to regain feeling in my finger tips or is this permanent damage?
