The doctor figures that it is hitting the palm, and parts of the finger, and the combo is what is causing the problem.
The sypathy nerves in the hand/finger are causeing the arteries to constrict. (this happens often...cold weather, injury, etc) but mine have taken too much of a beating, and have not relaxed.
the drug is supposed to get it to relax, and hopefully it will work, and I will not have to take it very long.
thanks for your thoughts.
