I'm new here so bear with me - not even sure where to post as I don't have diagnosis yet. I'm a veterinarian and thought I knew basic neurology fairly well - but apparently people are NOT animals! Anyway...

I'm 43, onset 5 1/2 months ago, had been "perfectly" healthy.
Everything has been symmetric/systemic.

Initially was middle toe numbness, progressed to top of feet, then patchy numbness up legs.

At same time was leg cramps and fascicularions - I do a lot of standing and they really ached if I stood still.
Also several times if I didn't move my legs "fell asleep".
Well, that numbness gradually went away back to my toes, but then developed whole body sensory loss.

First noticed scalp pain when out in hot sun, then encroaching sensory loss of head, face, then mid-body, then eventually everywhere. I can still feel most placed but not really pin-prick sensation.

Then came the lethargy - woke up one morning VERY lethargic, lasted ~2 days. I have had several more of those episodes, and more recently induced by exercise.
Along with sensory loss came ED - had weak sex for 3 nights, then next "unable to", followed by 2 days of severe lethargy.

My new symptom is muscular fatigue? example - I carried a 30# box for about 5 minutes, felt arms just trembling, then severe lethargy again for several hours. Now moderate lethargy is not going away, and legs are consistently weak.

Early on I also had more episodes of arms and legs falling asleep from seemingly benign positions. Oh, did I mention dry eyes now? (used to yawn and produce some tears - but not anymore).

ALL lab work has been normal. Ruled out diabetes, thyroid, Lymes, Myesthenia, etc... Both local and OSU Neurologists think Small Fiber but has no clue on the fatigue. EMG & NCS normal. I have some skin biopsies scheduled but doubt that will be helpful big-picture-wise. \

Never has been any real pain, but now I'm getting really scared with the weakness which does not seem to be going away.

Sigh. Anyone have any thoughts or direction for me?? THANX!!
