I think it is fair to say that exercise *can* be helpful- but it alone is not generally the answer to TOS.

lots of us can't exercise much due to vascular constrictions (e.g. exercise=really swollen arms). I don't get that, but if I do too much cardio i end up with a knot the size of my whole back in my back.... a 30 minutes walk around the block is usually too much for me, maybe I can do 15-20. A little cardio can be helpful, and WHILE i am exercising (if i manage not to cross the line into too much) it feels good and for a short while after, but then it hurts again.

and yes, having kids IS super stressful. Like Linda- my main exercising is laundry, cooking, and getting little kids in and out of the car!!!! It ISN'T sedentary...but it also isn't cardio. Mostly it is just nonstop BUSY and LOUD

J, i would suggest that If someone is telling you that just by exercising your TOS problems will be greatly reduced, well, I might not take that person toooooo seriously. Don't get me wrong- do exercise, it will make you feel better in general!!! But it will not make your compressed nerves/arteries stopped being compressed. Further help by PT, alexander, massage, chiro, and/or surgery is very likely to be neccessary.
