This thing with the numb finger tips just started. So I am just trying to feel my way and find a direction to go. I mentioned in my post the other problem I have is a severed phrenic nerve on my left side. Since posting here I traced a Doctor Abbot Krieger who was featured in a New Scientist article to his practice in Los Angeles. I am writing to him ask about a consultation. He is actually a plastic surgeon, but I will try to also see a neurologist in Los Angles.

I mentioned blood tests, because diabetes can also cause numb fingers. I'll need to confirm that my standard blood tests I have done every six months check for diabetes. I'm not so sure now.
