Here is a link to your intro which describes your symptoms for people who might want to review that:

My answer to your inquiry is to list all the things that I have found helpful as well as what problems I had that improved or not. I went over this a few times to make it thorough! I posted it in the thread on that topic:

In terms of outside help, it's time for you to switch up. Sounds like the spine specialist had his/her turn. Try a different vascular specialist, preferably one who lists TOS in their profile or is known to treat TOS. Try a different chiro, potentially using yelp.com or other sites to find a well reviewed one.
Don't wait for your next specialist to start trying things at home to improve your condition.
