Hey Fern, I get little electrical pulses in my thumbs down where the knuckle is at the front, I also notice at the same time that my vein is pumped and showing a fair bit. Also get stabbing pain in front of hand area half way between knuckles and wrist, like someone is driving something in can be quite painful. Apart from having artery, veins and nerves affected by TOS, I have C6 disc prolapse and C7 nerve compression.

Hope you feel better soon and get the answers from the Dr you are seeing, because we get very little help or understanding down under.
