To my understanding, you are definitely risking getting clots as you do have compression and you are not on blood thinners (that would reduce the chance of getting a clot), especially if you do exercises which further pinch the vein.

I did ask my surgeons about the activity I can do and they were happy with me doing whatever I want as long as I am anticoagulated. They don't want be to stop taking thinners if I don't do the surgery.

vTOS to nTOS could happen too, but to my understanding it is not very likely...

Regardless, I would definitely suggest you have somebody take care about your situation and advise what is the best option for you.

It is a bit difficult to judge as you haven't had any clots before, but you do have compression..
