Hi Chroma
GREAT LINKS.
I also think the whole breathing issue contributes so much to TOS.
I have never thought about this before or made a connection but as a child I suffered from pneumonia which took me months to recover from.
I now think that this is probably where I developed my poor ( shallow breathing) from.

QUESTION: Is this also why I occassionally suffer from dizziness and headaches??? .....Lack of sufficient oxygen, I think maybe so.

My main aim now is to focus on the breath.

Belly breathing really does take off so much pressure to the thoracic region.
However after years of the wrong kind of breathing it's quite tough to get used to and use the belly breathing technique.
Best wishes
