Tongue Twitching / Excess Saliva - Arterial TOS link?

[Btwitch]

I am a 42 year old male who has been twitching for a year.  The twitching started in the feet and calves but now occurs everywhere. I've had 2 clean EMG (March & August) and a number of clean neuro clinical exams - last EMG was on all 4 limbs but not Bulbar area.
However, the twitches have now started on the tip of my tongue even when at rest and on the face and lips. I am not having difficulty speaking or swallowing, but the tip seems tingly and twitches when at rest? I also have excess saliva being produced which started in March.  
I've just been diagnosed with bilateral Arterial Thoracic Outlet Syndrome which will require surgery on both sides to decompress arteries / nerves. As a result, its thought my hands have thinned and have lost some dexterity due to the Thoracic Outlet Syndrome.
There are so many mixed messages re. whether tongue twitching is benign or not so the question is;
In the absence of any clinical neuro findings and 2 x clean EMG's do you think the mouth symptoms I'm experiencing could be linked to the Thoracic Outlet Syndrome? Could they be vascular?
Do you think I should be seeking a second opinion from another Neurologist?
Any thoughts would be gratefully received, many thanks.
