"I think over-exertion, and bad ergonomics or body mechanics will make TOS worse, and anything that gives a whiplash-like effect. Anything that tenses the scalenes."
I think this is great advice to try and prolong the time you have until another possible surgery on the other side.
I too have bilateral ATOS and I am having my surgery tomorrow (wish me luck

) but I have been told by the surgeon that I will have to have the other side done within a year or two depending on the increase in symptoms. Which, sadly, have been steadily increasing.
I read your response on the post op experience, and I am happy that you are doing better- speedy healing to you!!
I know that folks having A-TOS are hard to find, but I sure am happy to know that I'm in good company around here!!
Take care,
Jocelyn
