Is facial numbness and pinpricks throughout body MS? All tests negative

[Odett15]

For the past 3 years I have been urgently trying to find out what is occurring in my body.  I started off by feeling a dull sensation from my lower right eyelid downward toward my upper lip.  I wouldn’t say it was numb because I never actually lost any sensation.  Then I started to feel the same dull sensation on my right two middle fingers and toes.  Sometimes it was simultaneous, sometime not.  This sensation comes and goes.  At times I go months without feeling it.  These flare ups usually don’t last more than a few hours, or days.
Now, the past few months I have noticed pin prick sensations throughout my entire body that has not gone away.  I usually do not feel this if I am laying down.  
I have had eye scan- negative, Brain MRI- negative, EMG-normal, MRI of cervical spine- negative.  I have also had extensive blood work done with my rheumatologist which all came back normal.  This hasn’t affected my strength as of yet.  I am somewhat of an avid Olympic lifter and have kept track of my personal bests for the past 4 years and all lifts have gradually gotten heavier.  
This is of great concern to me because my mother is currently in the process of trying to determine if she has MS (MRI positive for legions along with tingling in her left arm and leg).  I am currently 29 years of age with a one year old son and would love some advice on this subject. Please.
