@ossobuco,
Ok, I'm noting this in case I somehow forget my next appointment date, I can check here -
April 22nd at 11 am, main hospital, Dr. So and So for the EMG and NCS.
Emg isn't electromyelogram as I typed, but myogram. And yes, medicare already ok'd it.

Meantime they gave me two superduper splint wrap things, one each hand, to wear at the least at night. (I had sprung for one at the local pharmacy a couple of months ago, but it wasn't as, mm, good as these, and I could still massacre my thumb with a wrong twist.. but I think these things are better than nothing.
On carpal tunnel, should that turn out to be the problem,

Lots of good info (it seems to me) on that site.
