Hi Jacquelina! I do not have TOS but I have had a breast reduction. I wondered what you think is might do to help your TOS. I do not know anything about TOS. I can offer the fact that I had extremely painful back and shoulder aches..especially lower back. The reduction was not an easy surgery for me, however everyone is different. I n the long run I can say that I would go through it all over again. I went from an F cup to a DD and I went from alot of pain to practically no problems with my back and shoulders again. I cn len over nd come back up again. Before the surgery I had to rub my back and ease myself up slowly...very painful. Now I feel alot better! Hope it helps. Dorrie
