I, too, am new, but keeping up with you. I know you read a lot, as I do and are familiar with the saying"Ignorance is Bliss". Don't you wish that sometimes? You were correct in one of your posts that spoke of error in EMG's. Mine were both differing because one failed to warm up my calf.
It seems to me you are doing enough right now. Just be sure you have a trained tech, preferably the neurologist that you trust, actually performing both tests. Try not to be anxious as that can influence results. I know that is easier said than done.
Sounds like you are OK so far, and somatization disorder or conversion disorder would be my diagnosed of choice(for me, not saying your head is your problem), unfortunately, they are not in the picture for me because of my symptomology
Try and get through one hurdle at a time. Get your results on your EMG,NCS.
By the way, how is your diet and weight stability?Drug and alcohol intake can also cause weakness(Statins have been linked to muscle damage and weakness,especially 80mgZocor).Vitamin deficiency can cause problems, too.(usually, not always, if your diet is good, that should be OK).
Try your best to be positive.
