Thank you very much for your reply.
Currently the TOS on the right arm that blocks the blood flow when my wife raises her arm doesn't bother her too much, she tries to avoid that but only because she was told it's not good for her, she doesn't feel any discomfort with that.
The TOS on the left arm is quite different. It affects her daily life completely as there is always almost no blood flow there. There is not much to avoid in order to irritate the area as any kind of activity with the left arm causes pain almost immediately...

I would love to hear more about the IR therapy you mentioned.

Thanks again for your kind words.
