Mrs D:

I wonder if I might actually have a Thoracic Outlet Syndrome for the following reason. In reaching this I noticed that it can be associated with a "Gilliatt-Sumner" hand.

This is a hand in which there is muscle wasting in the fleshy muscle at the base of the thumb. On one of my hands that is exactly what appeared a number of years ago. When I open my hand widely and then look at the palm side there is a deep grove in the muscle at the base of the thumb that does not hurt.

However, this does not appear on the other hand.

Thoughts?
