On Feb 4 2016 the left side of my body went numb--not paralyzed, but numb, like you've had dental work and had the "deadening" shot, and it has started to wear off, but doesn't. I have seen my primary care physician, a chiropractor, a neurologist, an orthopedic surgeon and a neurosurgeon. I have had brain and cervical spine x-rays and MRIs, and there is no "structural" cause for the numbness they can see.
