I will add, there is no one thing that works for everyone..it takes some experimenting to find what works for you..
But if something you try increases your pain/discomfort for more than a few days, you either pushed too much or it isn't the thing for you..

Baby steps to adding any activity is the best way to move forward.. pushing too hard will set you back..

Many with TOS have the delayed pain, a day or so after the activity.. (even a dr visit or PT) so that is something to be aware of also..
