Hello and welcome! Your story is almost identical to mine. I had the exact same evolution, first hand, wrist pain, then it spread to the shoulder and left arm. I can also describe that tight sensation on the arms like a sweater with tight sleeves that was making me immobile and awkward.

Because I didn't know about TOS I went trough an unnecessary wrist surgery that obviously did not fix anything, got tested for MS and anything else under the sun.

I would recommend that you see a TOS specialist, there is no point in wasting more time and money on unnecessary treatment/opinions.

Can you tell which city you live in so that we can make a recommendation for a specialist?

I have already had surgeries on both sides and recovering.
