Do you have any discoloration in the arm or fingers?

My understanding of some TOS is that it can result from a blood clot in a vein in the shoulder area. When that happens, nerves may be impacted with poor circulation, etc.

So some evaluations involve evaluating the blood vessels in the area. You might think about this aspect too, since you don't lift weights (move furniture or luggage), have an injury, swim too much, or throw balls etc.(sports)

Females on birth control pills can have odd blood clots in strange places, especially if they have a genetic error in the family to favor these. Some get the clots in legs, others, in deep pelvic veins, and some get them in the brain and elsewhere.
